Evidence suggests that children with selective mutism (SM) display significant aberrations in auditory efferent activity at the brainstem level that may underlie inefficient auditory processing during vocalization, and lead to speech avoidance. The objective of the present study was to explore auditory filtering processes at the cortical level in children with SM. The classic paired-click parad...

Selective mutism (SM) is a rare and interesting condition that has been associated with a wide variety of childhood psychiatric conditions. Historically viewed as more of an oddity than a distinct diagnostic entity, early conceptualizations of the condition were based largely on case studies that tended to link SM with oppositional behavior. More recently, controlled studies have enhanced our u...

We describe a case of akinetic mutism mistaken as coma. A 77-year old lady presented with apparent unresponsiveness. In fact she responded when stimulated. She subsequently developed movements typical of clonic perseveration, erroneously treated as seizures. She also had features of a frontal lobe syndrome. Initial CT scan showed no abnormality; it was only after an MRI scan that a diagnosis of...

objective: to compare the clinical profile and pattern of catatonic symptoms of patients with schizophrenia and mood disorder. method: records of 13,968 patients seen between 1983-1985 and 2003-2005 were reviewed for symptoms of catatonia by resident doctors in psychiatry. cases in which the diagnosis were schizophrenia or mood disorder were then noted. socio-demographic and clinical features w...

bral grey matter was normal. The posterior borders of these lesions were formed by the caudate nuclei, the anterior parts of the internal capsules being spared. The lesions reached the parietal periventricular areas. The necrotic areas were characterised by extensive loss of myelin with myelin laden gitter cells. On both sides a substantial number of neurons in the ventromedial parts of the put...
