Four patients had a positive personal history for parasomnias and two- a positive family history. Personal history was positive for parasomnias in two patients. Family history was positive for parasomnias in two patients, for nocturnal groaning in one patient, and for sudden infant death syndrome in one patient. Eight patients were reporting a family history positive for parasomnias and three for nocturnal groaning. Catathrenia is associated with a positive personal or familial history for other parasomnias. There is no drug medication available for catathrenia. Empirical pharmacological treatments with dosulepine, trazodone, clonazepam, paroxetine, carbamazepine, gabapentin, and pramipexole have been unsuccessful or refused. The efficacy of the nCPAP ventilation is still debated. In particular, nCPAP treatment seems effective only when noisy breathing during sleep, diagnosed as catathrenia, is related to the co-existence of expiratory and inspiratory flow limitation with obstructive apneas or hypopneas and consequent intermittent hypoxia.
