Infectious Causes Of Parkinsonism

The association of human immunodeficiency virus (HIV) infection and movement disorders has been recognized since the first descriptions of neurological complications of HlV-associated AIDS (58). Secondary parkinsonism has been reported by various authors as case reports, but Mattos et al. (59) have reported movement disorders in 28 HIV patients of whom 14 patients had parkinsonism. The mean age at onset of parkinsonism was 37.2 yr (range 25-63). They report mean Hoehn and Yahr scale of 2.5...

Metabolic Causes Of Parkinsonism

Important metabolic causes of parkinsonism include hypothyroidism and parathyroid dysfunction. Patients with hyperparathyroidism have clinical presentation identical to that of idiopathic PD, but the syndrome is levodopa resistant. The symptoms, however, may be relieved after resolution of the parathyroid dysfunction by surgical removal of the parathyroid adenoma. Hypoparathyroidism may also cause levodopa unresponsive parkinsonism (69,70). Bilateral striopallidodentate calcinosis, also known...

Neuropsychiatric Symptoms In Multiple System Atrophy

MSA is clinically characterized by the variable combination of autonomic failure, parkinsonism, cerebellar ataxia, and pyramidal signs, and includes the previously called striatonigral degeneration (parkinsonian features predominate), sporadic olivopontocerebellar atrophy (OPCA) (cerebellar features predominate), and the Shy-Drager syndrome (autonomic dysfunction predominates). Histologically, all subtypes of MSA show glial cytoplasmic inclusions in oligodendrocytes of the cerebral white...
