The effect of bifemelane hydrochloride on dementia in the elderly was studied in thirty-one patients having cerebrovascular disorders. Alzheimer's disease, Parkinsonism and related diseases. The drug (150 mg) was administered orally three times daily for 10 weeks. The final global improvement rating was 77.4% for all patients. The rates of improvement for Alzheimer's disease were higher than those for cerebrovascular disorders, suggesting that this drug affects Alzheimer's disease through a cholinergic potentiating action. Psychotic, neurological and subjective symptoms, and the activity of daily life, were rated before, during and after treatment. All mean rates of improvement were based on observations made in the 4th week after the start of treatment. Improvement rates for global symptoms were more than 80% for emotional incontinence and prejudice or querulous attitudes toward the nurses, and in headache, tinnitus and dizziness among the subjective symptoms. The improvement in intellectual function was evaluated by the dementia rating scale for the elderly (DRSE), and a significant increase was found in DRSE after treatment with this drug. Side effects attributable to the drug were noted in one patient developing urticaria. It is thus suggested that bifemelane hydrochloride is useful in the treatment of different symptoms of dementia.

Toxoplasmosis encephalitis in patients with human immunodeficiency virus may progress rapidly with a potentially fatal outcome. Less common neurological symptoms associated with this are Parkinsonism, focal dystonia, rubral tremor and hemichorea-hemiballismus syndrome. A 58 year old woman suddenly lost consciousness and was admitted to the emergency service. Her medical history was unremarkable, except for frequent headaches in the last year, recurrent herpes simplex skin lesions and an episode of urticaria. A computer tomography scan showed supra and infra-tentorial lesions on suggestive of cerebral toxoplasmosis. Both Toxoplasma gondii and HIV tests were positive. In the intensive care unit, antiparasitic and antiretroviral drugs were administered, and she recovered from the coma after six weeks but presented with tetraparesis, diplopia, and depression. The LCD4 count increased from 7 to 128/mm3. The neurological lesions slowly resolved over the next two months, although postural instability, rigidity, bradykinesia and predominantly left side tremor persisted. Mild improvement was achieved after the administration of levodopa. Associated Parkinsonian syndrome in HIV patients is a rare condition, explained by the location of the brain and basal ganglia lesions, and by the observed effect of Toxoplasma gondii which increases dopamine metabolism in neural cells. Early HIV diagnostic and treatment are necessary to prevent neurological disability.
