A very musical psychopathology – from intrusive musical imagery, to musical obsessions and hallucinations

Introduction The semiological spectrum that encompasses musical imagery is a very confusing field, as it often difficult to understand the nature of underlying psychopathological phenomenon from patient’s description. Objectives purpose authors explore reviewing, distinguishing and organizing concepts such Intrusive imagery, obsessions, hallucinations, pseudohallucinations palinacousis. Methods A brief non-systematized review presented, using literature available on PubMed Google Scholar. Results (earworms, ohrwurms , or involuntary imagery) occur in more than 85% general population, without pathology ear disease. It involves repetition 15-30 seconds fragment music/tune, persisting like looping soundtrack, not being aversive. Musical obsessions are rare form intrusive occurring either with other symptoms Obsessive Compulsive Disorder isolated (“The stuck song syndrome”). recurrent, persistent, intrusive, unintentional, time consuming causes distress functional impairment (although ego-dystonic aversive usually visual are); preserved insight. hallucinations only 0,16% hospital; they can be linked psychiatric diseases, but common neurological diseases (cerebral lesions, Parkinson’s disease, delirium, drug induced…). They reported less controllability, lyrical content, lower familiarity, forms inner music; perceived arise an external source interpreted veridical. Pseudohallucinations after severe hearing loss, hallucinogen intoxication psychotic non-psychotic disorders (as dissociative states borderline personality disorder). inner/subjective space, insight fluctuate. palinacousis associated electroencephalogram neuroimaging abnormalities, structural brain pathology. There perseveration (echoing) auditory stimulus occurs cessation stimulus. Conclusions rash classification lead misdiagnosis (for e.g. interpreting obsessive hallucinatory phenomena rendering organic undiagnosed) institution inappropriate therapy. important carefully these when patients present complaints, taking some characterize them.
