Changes in the electrical cerebral activity, especially in frontotemporal regions, have been described after using the Superficial Neurostimulation Application (SNSA) in upper and lower limbs. The use of this technique is associated with emotional equilibrium and predisposition for a positive mood. Its application clinically improves hostility and anxiety symptoms.

To compare the electrical changes observed after the use of SNSA with other techniques of mental concentration: Mindfulness (mental attention without judgment) and a technique based on the emission of a sound.

SNSA topology system: uses electricity through superficial electrodes placed on feet and hands and an electrode over the 7th cervical vertebra; Digital encephalogram; Faraday cage.

Mindfulness and SNSA techniques show similarities regarding the alpha rhythm's frequency in frontal regions (Figs. 1 and 2) compared to a different mental concentration technique (Fig. 3).

Further analysis would be required.

Forty-three-year-old male diagnosed with Klinefelter syndrome and showing radiological findings suggesting a demyelinating pathology who presents several psychiatric manifestations including megalomaniacal ideation, delusion, lack of impulse control and behavioral alterations.

Forty-three-year-old male diagnosed with Klinefelter syndrome at the age of 31, presenting several psychiatric pathologies since adolescence: delusions, megalomania, mood fluctuation, and high impulsiveness. The patient had a poor therapeutic response to anti-psychotic drugs and ECT. He was hospitalized up to 9 times, but the full control of the symptomatology was not achieved. During his last hospitalization, a MRI revealed lesions compatible with a demyelinating pathology.

A higher prevalence of schizophrenia spectrum disorders has been described among patients suffering from Klinefelter syndrome, which might explain the role of the X chromosome in the susceptibility to psychiatric disorders, particularly to psychosis. Furthermore, the brain structure alterations presented by patients suffering from Klinefelter syndrome are similar to those described among schizophrenic patients: small brain volume, lateral cerebral ventricular enlargement and reduced temporal gyrus, amygdala, insula and cingulate cortex. Patients suffering from multiple sclerosis are more prone to psychiatric disorders, such as mood swing, aggressiveness or psychosis, which are not concurrent with the physical progression of the disease, sometimes being its first manifestation. Even when being patchy and multifocal, demyelination seems to be concentrated in the frontal lobes, related to the cognitive and affective functions and the personality.

Both multiple sclerosis and Klinefelder syndrome may alter the brain structure, mainly in the frontal lobe, and predispose to psychiatric disorders.

Although cannabis is very widespread worldwide, its brain toxicity is poorly understood. The neuroretina is an accessible extension of the brain and could be a relevant site for investigating neurotransmission abnormalities in neuropsychiatric disorders. The retina has a functional endocannabinoid system involved in the regulation of retinal neurotransmission. In animals, the modulation of this system led to retinal dysfunctions measured with the electroretinogram (ERG).

To assess whether the regular cannabis use could affect the neuroretinal function.

Assessments of the neuroretinal function in cannabis users compared with controls.

Recordings of pattern, flash and on-off ERG were performed in 55 cannabis users and 29 controls. The amplitude and implicit time of the following waves were evaluated: N95 (pattern); a – and b – (flash); a –, b- and d1 – (on-off).

Cannabis users showed a significant increase in implicit time of the waves N95 (P = 0.0001), a- (P = 0.029) and b – (P = 0.002) for the flash ERG and b – (P = 0.016) and d1 – (P = 0.027) for the on-off ERG, compared with controls. No significant difference was found between groups in terms of wave's amplitudes.

These results show a delay in the response of cones, bipolar and ganglion cells of the on and off pathways to constitute a delay of ≈ 6 ms in the transmission of information from the retina to the brain in cannabis users. Cannabis could disrupt the regulatory role of the cannabinoid system and impair retinal glutamatergic neurotransmission. The consequences on visual perception should be explored in future studies.

Human embryos are most susceptible to exogenous effects during the first weeks of development.

Study the effects of prenatal alcohol intoxication on morphometric measures of developing vessels in the human embryonic and fetal cerebrum.

Embryos and fetuses (7–12 weeks): 23 obtained from alcoholic women with stage II alcoholism (the experimental group) and 30 from healthy women (the control group). The research involved electron microscopy, computer morphometry, parametric method of variational statistics and Scion software to determine mean vascular cross-sectional area, the relative cross-sectional area of vessels, the number of vessels per unit area, and the perimeter of vessels.

From 10 weeks, vessels in the human brain start to differentiate into arteries and veins. At 12 weeks, capillary basal membranes were already clearly visible. We established a series of characteristics distinguishing brain tissues in the experimental group vs. that in controls: mean vessel cross-sectional areas and vessel perimeters were significantly reduced by 11 weeks vs. controls. The tendency persisted at 12 weeks. Relative vessel cross-sectional area in the experimental group was greater than in controls.

There is significant evidence that HIV is brain degenerative and long-term infection can impair cognitive functioning. In South Africa, alcohol remains the dominant substance of abuse and lifetime alcohol dependence has been found to impair memory, executive function and visuospatial capabilities. The individual liability of alcohol and HIV on neurocognitive function have been well demonstrated, however there is relatively little evidence of the potentially aggravating effects of this dual burden on neurocognitive outcomes.

The present study is ongoing and sought to identify the effects of hazardous alcohol use on neurocognitive functioning in the context of HIV infection.

To describe the association between HIV and harmful alcohol use on neuropsychological test performance in a cohort of adults in the Western Cape of South africa.

participants (n = 50) were tested using a battery of neuropsychological tests sensitive to the effects of HIV on the brain. Self-reported alcohol use was recorded using the alcohol use identification test (AUDIT). Results The sample consisted of 47 females and 3 males. All participants were HIV-positive and on antiretroviral therapy. A total of 23 (46%) participants reported no alcohol use and 27 (54%) reported drinking alcohol on the AUDIT.

revealed a significant difference between groups on the Stroop colour word test, with poorer performance evident among the alcohol users (P = 0.008).

Alcohol use in the context of HIV infection contributes to poorer executive function. These preliminary data provide evidence for a synergistic relationship between HIV infection and alcohol use.

Mourning the death of a loved one, the loss of social aggregation or familiar, or any trauma may not follow the normal process when has any kind of complication In these cases of the complicated mourning, a person may develop or manifest dissociative behaviors, like diogenes syndrome or the misery senile syndrome.

To investigate the presence of unauthorized mourning, complicated or not elaborate as triggers of diogenes syndrome and misery senile.

To develop this research we use the systematic literature review, following the process of research, cataloging, careful evaluation and synthesis of the documentation associated with the method of thanatological hermeneutics.

Thanatology is useful tool in scientific and clinical research and care for patients with diogenes syndrome. The need for safety against the distress of fear of the future and loneliness is at the origin of compulsive hoarding. If the mythical diogenes lived in Athens a Spartan life, living in a barrel, as the character Chespirito of Roberto Bolaños (Fig. 1), the carriers of this syndrome follow the opposite path accumulating objects to achieve a sense of stability.

There is a significant presence of unresolved grief in the history of the psychiatric patient with diogenes syndrome.

Hoarding often occurs without the presence of obsessive-compulsive disorder (OCD), showing distinguishable neuropsychological and neurobiological correlates and a distinct comorbidity spectrum. Furthermore, it presents itself secondarily to other psychiatric and neurobiological disorders. Therefore hoarding disorder has been included as independent diagnosis in DSM-5.

We aim to expose the possible organic etiology of a hoarding disorder case with atypical presentation.

We present a case of a 48 years old male patient who was brought to the hospital by the police after being reported for unhealthy conditions in his home. In the home visit paid by the Social Services an excessive hoarding of objects and trash was detected. A possible hoarding disorder was diagnosed in the psychiatric assessment. Among other diagnostic test, a brain CT was conducted, in which a frontal meningioma was identified. After surgical treatment, hoarding symptoms diminished significantly.

A significant part of the hoarding disorders are attributed to primary psychiatric disorders, resulting in potentially treatable organic pathology going unnoticed.

It's important to rule out organic etiology before proceeding to make a definitive hoarding disorder diagnosis, optimizing that way the treatment options.

Previous research suggests that hoarding aggregates in families and is associated with health, safety risks and family problems. Hoarding symptoms appear to be more common among first-degree relatives of people who hoard. A predominance of shared hoarding disorder has been observed among female relatives.

We present an atypical case report describing hoarding symptoms among first-degree male relatives who present two different subtypes of hoarding disorder.

We report the case of a 38 years old male patient, attended for the first time by the mental health services at the age of 22, and being diagnosed of severe OCD at that moment. In the home visit paid by the social services, an excessive object hoarding was observed, including the presence of over 40,000 books.

Moreover, they found a 38 years old man looking severely deteriorated; when they ask him about it, the patient's father admits to having been isolated in the house for almost 14 years. Hoarding history was gathered, through the acquisition of various objects by the patient's father, dating back to over 30 years ago.

The harmonic coexistence for over a decade between two patients affected with a hoarding disorder with two different clinical setting subtypes was only made possible by the complementary nature of their symptoms.

The hoarding disorders amongst more than one person living under the same roof are uncommon, can present themselves in both genders and can exhibit different symptoms.

This is the case of a 73 year old woman with a late onset, severe and refractory obsessive-compulsive disorder who experimented a sudden remission after a frustrated suicide attempt.

Our target is to make a reflection about the relation between traumatic closeness to own death and neurosis spontaneous remission.

Patient has been interviewed and her medical record studied.

Patient's psychiatric history shows major depressive disorder, recurrent (ICD 10 CM-F33). Patient is a housewife with primary education. In her psychobiography distinguish a conflictive relationship which probably acted as a trigger for obsessive-compulsive symptoms. These symptoms include obsessive thoughts of contamination, ritual hand washing and avoid contact with others people. In the course of the last 10 years, since the OCD (ICD 10 CM-F42.2) diagnose, the patient has been through a wide therapeutic arsenal, from cognitive-behavioural psychotherapeutic interventions to psychopharmacological treatment, resulting with limited effectiveness. The last treatment was fluoxetine 200 mg (0–0–1) and pregabalin 300 mg (1–0–1). Subsequently, the patient underwent a failed suicide attempt by hanging. After physical recovery, all OCD symptoms had subsided.

Traditionally, literature and philosophy considered catharsis as a purifying experience, and Breuer and Freud introduced this concept in modern psychology as a therapeutic method. More recent authors as Yalom have correlated the closeness to death as a stress factor with radical change in life's perspective and attitude. Although current research presents contradicting data about healing effectiveness through a catharsis processes, this case exposes a clear example of positive outcomes in this assumption.

A possible role of second messengers, such as cyclic adenosine monophosphate (cAMP) signalling, in the development of obsessive-compulsive disorder (OCD) has been recently postulated.

The aim of the present study was to explore and to compare the adenylate cyclase (AC) activity in both basal conditions and after the stimulation by isoprenaline (ISO) in platelets of OCD patients and healthy control subjects. The AC activity was measured both in the absence and in the presence of α- and β- adrenoreceptor antagonists.

Forty patients were included in the study and compared with healthy volunteers. Biological assays were carried out with a method developed by us.

The basal AC activity was similar in both groups. The addition of 10 μM ISO enhanced significantly (P < .05) platelet basal AC in both groups. A stimulatory response following ISO in all subjects even without α-antagonists was also observed.

No difference in the basal AC activity in platelet membranes of healthy subjects and OCD patients was found. Our findings showed that there is an inhibitory component of ISO effect on platelet AC, due to the agonist interaction with α2 receptors, at its higher concentrations (>1 μM), as well as a condition of supersensitive β-receptors. Our study suggests the presence of cathecolamine system disturbances in OCD.

Thirty year old man with obsessive clinic of years of evolution, with worsening in recent months treatment with 200 mg sertraline.

In both cases treatment with oral aripiprazole it was associated with a dose of 5 mg daily with improvement in obsessive symptoms.

The efficacy of aripiprazole as adjunctive drug treatment and obsessive anxiety is observed. However, we must take into account the potential risks posed as neuroleptic malignant syndrome and QTc prolongation.

Aripiprazole is an antipsychotic which has a novel mechanism of action to be a partial agonist of dopamine D2 receptors. This fact has led to its inclusion in the group of antipsychotics called third generation, also called partial dopamine agonists, dopamine stabilizers or “dopamine-serotonin modulators system.” Its most common side effects such as nausea, headaches, agitation and akathisia were observed in studies on schizophrenia, schizoaffective disorder and bipolar disorder. Unlike other atypical antipsychotics, is considered a relatively neutral drug to weight gain, hyperprolactinemia, changes in metabolic parameters and sedation.

Obsessive-compulsive disorder (OCD) has high rates of comorbidity with mood disorders, mainly major depressive disorder (MDD). Symptoms of depression are usually secondary to severe and disabling OCD. Electroconvulsive therapy (ECT) has been an effective and well tolerated therapeutic alternative in the management of refractory MDD. Other neuromodulation techniques, such as repetitive transcranial magnetic stimulation (rTMS), have well known efficacy in MDD and also have shown positive results, in clinical trials, treating other psychiatric disorders such as OCD.

To determine the efficacy of combining rTMS, ECT and clomipramine in the treatment of severe OCD with comorbid severe MDD.

The authors report a case of a 54-year-old male patient diagnosed with severe OCD for 23 years. He has been submitted to several drug treatments and intensive cognitive-behavioural therapy (CBT) always with poor response. The patient was admitted in the beginning of 2016 in our inpatient unit. Besides continuing drug treatment (clomipramine IV) and CBT, he was submitted to 12 ECT sessions during one month (3 sessions per week) and to daily sessions of rTMS during the following month.

Outcome measures were obtained using Y-BOCS for OCD and HAM-D for depression.

Our patient responded to ECT with mood improvement after session 4 to full euthymic state at the final session. He also responded well to rTMS with Y-BOCS score reduction.

Combined ECT and rTMS treatment with clomipramine IV and CBT was effective in our patient with a severe form of both disorders (OCD and MDD).

Cognitive behavioural therapy (CBT) is the first-line psychological treatment for Obsessive-Compulsive Disorder (OCD). However, 30% of individuals have a null or partial response. Preliminary evidence suggested that Acceptance & Commitment Therapy (ACT) may be effective. No study investigated whether the association of CBT with ACT may improve outcomes of CBT alone.

This paper presents the protocol of a trial where individuals with OCD will be randomly assigned to CBT alone or CBT plus ACT. Primary endpoints will be the number of individuals meeting OCD diagnostic criteria at post-treatment and follow-up. Secondary endpoints will be self-reported depression, anxiety, disgust and guilt, and obsessive beliefs. It is hypothesized that CBT plus ACT is associated to fewer individuals meeting OCD criteria and greater reductions in secondary endpoints.

A single-blinded superiority randomised design will be used. Primary/secondary outcomes will be administered at baseline, post-treatment and 6-month follow-up. Treatment duration will be 25 weekly sessions in both conditions. Individuals (age ≥ 18 years) with OCD diagnosis will be recruited at mental health services in a 60.000 inhabitants area in Italy. Chi squared will be computed to test group differences on OCD diagnosis. ANCOVAs will be calculated entering baseline scores as covariates, group allocation as random factor and primary/secondary outcomes as dependent variables.

To obtain a medium effect size, 80% power and 0.05 significance, a priori power analysis suggests inclusion for at least 34 individuals as total sample.

A description of the protocol will be provided. Strengths and potential limitations will be addressed.

Cognitive theories of Obsessive–Compulsive Disorder (OCD) have identified six types of beliefs, which have a role as vulnerability and maintaining factors: Inflated sense of responsibility, Threat overestimation, Importance of thoughts, Control of thoughts, Perfectionism and Intolerance for uncertainty. As previous research showed that strong obsessive beliefs are linked to severe OCD symptoms, it could be hypothesized that they act as prognostic factors of negative response after cognitive behavioural therapy (CBT). However, poor research investigated this aspect.

The aim of the current study was to examine which obsessive beliefs could predict a worse response after intensive CBT in a group of inpatients with medication-resistant OCD.

Forty inpatients [mean baseline Y-BOCS = 26.70, SD = 7.01] with medication-resistant OCD underwent 5-week intensive CBT including daily and prolonged exposure and response prevention (2.5 hours in the morning, 2.5 hours in the afternoon). All individuals have had inadequate symptom response after prior serotonin-reuptake inhibitor trials. The Y-BOCS, BAI, OBQ-87, and BDI-II were administered at baseline and post-treatment.

Inpatients who endorsed stronger intolerance for uncertainty, measured by higher scores on the OBQ-87 Intolerance for uncertainty scale, showed worse response after CBT, measured by having still higher Y-BOCS scores at post-treatment (β = 0.37, t = 2.48, r2 = 0.14, P < 0.05). No effect of the other beliefs emerged.

Current data demonstrated the role of intolerance for uncertainty as predictor of negative response after intensive CBT for resistant OCD in inpatient setting. Augmentation strategies should be introduced to improve outcomes of inpatients with intolerance for uncertainty.

The objective of investigation was to determine whether patients with obsessive-compulsive disorder (OCD) resistant to drug therapy may improve their condition using intensive, systematic cognitive behavioural therapy (CBT) lasting six weeks and whether it is possible to predict treatment outcome using clinical and selected psychological characteristics.

From 66 OCD patients fifty-seven completed program. The diagnosis was confirmed using the structured mini international neuropsychiatric Interview. Patients were rated using the objective and subjective forms of the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), objective and subjective forms of the Clinical Global Impression (CGI), Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), dissociative experiences scale, 20-item Somatoform dissociation questionnaire and sheehan disability scale before treatment, and with subjective Y-BOCS, objective and subjective CGI, BAI and BDI at the end of treatment. Patients were treated with antidepressants and daily intensive group CBT for six weeks.

During 6-week intensive CBT program in combination with pharmacotherapy, there was significant improvement in patients suffering from OCD resistant to drug treatment. There were statistically significantly decreased scores of scales assessing severity of OCD symptoms, anxiety, and depressive feelings. A lower treatment effect was achieved specifically in patients who (a) showed fewer OCD themes in symptomatology, (b) showed higher level of somatoform dissociation, (c) had poor insight and (d) had a higher initial level of overall severity of the disorder. Remission of the disorder was more likely in patients who (a) had good insight, (b) had a lower initial level of anxiety and (c) had no comorbid depressive disorder.

Misophonia refers to a condition in which there is a strong aversion to certain sounds, in response to it the person reports unpleasant emotional experiences and autonomic arousal.

To present the case of misophonia carrier and discuss diagnostic features.

Case report and literature review.

Female, 32 years old, married, two children. In anamnesis reported obsessional symptoms (Check doors and windows, concerned with order and symmetry of objects; read all that lies ahead, pull the hand two or three times on mobile) since adolescence. Also reported triggering situations of anger: intolerance to some noises and sounds, like chewing third, mobile keyboard, click the “mouse” computer, printer and rub hands. In the presence of these noises, she tries to move away, and already tried to attack physically relatives and insulting co-workers. She was treated with escitalopram and re-evaluation after thirty days, reported partial relief misophonia and reduction of obsessional symptoms.

The condition was first described in the early 2000s by two audiologists, and has become the focus of interest in the field of psychiatry. Some reports suggest that misophonic symptoms may be part of other conditions such as Tourette's syndrome, obsessive compulsive disorder and generalized anxiety disorder. Specifically, the characteristics shared between misophonia and OCD, as the relief of discomfort associated with avoidance behaviour suggest that the condition is part of the obsessive-compulsive spectrum, which seems to happen with the case described above.
