A 40-year-old woman developed high fever and headache. Five days later, she was admitted because of consciousness disturbance and tremulous movements in upper extremities. The paired sera showed more than fourfold elevation in complement fixation titer to Japanese encephalitis virus. She was diagnosed as Japanese encephalitis from the clinical features and serological tests. Magnetic resonance imaging (MRI), which was performed about seven months after the onset, revealed abnormal intensity areas bilaterally in the thalamus, hippocampus, substantia nigra, globus pallidus and white matter around the lateral ventricle. Eight months after the onset, she was left with bradykinesia, disturbance of rightening reflex, emotional lability and impairment of recent memory with a long period of amnesia, including not only her illness and subsequent events but also about several years before her illness. The characteristic memory dysfunction seems to be due to disorder of bilateral hippocampus, where MRI revealed abnormal intensity areas. And disorder of medial thalamic nucleus would be related to emotional liability. The relation between the clinical features and MRI findings is also discussed.

We are presenting an uncommon case of cerebral tumor whose major manifestation was parkinsonism. The patient was a 50-year-old woman presented with a 5-month history of tremor of the right hand, particularly at rest, and headache. On neurological examination of March, 1987 there were: slight right-sided hemiparesis with symmetrical hyperreflexia; discrete bradykinesia in combination with cogwheel rigidity also on the right-side; resting tremor of the right hand; and bilateral papilledema. The neuropsychological examination disclosed: nominative aphasia, impaired recent memory and right-left disorientation. The computed tomography showed a large, left frontotemporal tumor. Angiograms of the left internal and external carotid arteries revealed a tumor blush in the left frontotemporal region supplied by a enlarged middle meningeal artery. An electromyogram revealed a 4-6 HZ tremor on right hand. A course of treatment with dexamethasone 16 mg/day and levodopa plus benzerazine (500 mg/day) was unsuccessful. A left fronto-temporo-parietal craniotomy was performed and an attached sphenoid wing tumor was macroscopically completely removed. Microscopy indicated that the tumor was a meningioma. Postoperatively, the patient made an uneventful recovery. After two weeks, her right-sided palsy and parkinsonism had disappeared, and neuropsychological deficits improved. Two months later there was no abnormalities on neurological and neuropsychological examination. It was concluded that the parkinsonism was caused by mechanical pressure on the basal ganglia.

Six males and one female with chronic tic disorders, whose ages ranged from 12 to 31 years, were evaluated before treatment, after 1 month on placebo, after a single 10 mg nifedipine dose (three patients), and monthly while on flunarizine 10-15 mg (mean dose of 13 mg). None of the patients receiving nifedipine improved, but treatment with flunarizine significantly decreased both motor and phonic tic severity and frequency in all but one patient. Side effects included mild transient headaches in one patient, depression in one, and bradykinesia in two. Although a double-blind study is essential to validate our findings, results suggest that flunarizine is a useful drug in the treatment of Gilles de la Tourette syndrome.

Manganese (Mn) poisoning, a well-known hazard in miners and industrial workers, shares many features with Parkinson's disease. Two young agricultural workers with a parkinsonian syndrome, who mentioned exposure to the fungicide maneb (manganese ethylene-bis-dithiocarbamate), led us to investigate a new possible source of Mn intoxication. Fifty male rural workers with occupational exposure to maneb were compared with 19 rural workers without fungicide exposure. We noted significantly higher prevalence of plastic rigidity with cogwheel phenomenon, headache, fatigue, nervousness, memory complaints, and sleepiness in the exposed group. In addition, we saw other neurologic signs, such as postural tremor, cerebellar signs, and bradykinesia, although without statistical significance. The data suggest that occupational exposure to pesticides containing Mn is a possible source of Mn intoxication of the CNS.

Cyclosporine has been associated with various neurological side-effects including postural tremor, seizures, headaches, encephalopathy, cortical blindness, and visual hallucinations. We describe here two patients who developed parkinsonism, with rest tremor and bradykinesia, after receiving cyclosporin A following allogeneic bone marrow transplantation. The patients did not have pre-existing neurological disorders, and had not received significant amounts of dopamine-blocking drugs. One patient improved markedly with Sinemet (carbidopa-levodopa), while the other (who did not tolerate Sinemet) improved with decrease in cyclosporine dosage. The relation of the parkinsonian symptoms to cyclosporine therapy and lack of other evident causes for the symptoms, suggests that parkinsonism may be an occasional consequence of cyclosporine.

Progressive multifocal leukoencephalopathy (PML) is caused by replication of JC virus in oligodendrocytes of immunocompromised patients. Common manifestations are focal motor and sensory deficits, gait abnormalities, speech and language disturbances, cognitive disorders, headache, and visual impairment. Although the occurrence of movement disorders is rare in PML, bradykinesia, rigidity, dystonia, myoclonic jerks and myoclonic ataxia have been described. Head tremor associated with PML has not been previously reported. We report two cases of PML in whom head tremor was present.

Welding fume contains manganese (Mn) which is known to be bio-available to and neurotoxic for the central nervous system. Although an essential metal, Mn overexposure may cause manganism, a parkinsonian syndrome. The present welder study sought to improve the clinical portrait of manganism and to determine dose-effect relationships. The welders were employed in the construction of the new Bay Bridge (San Francisco) and welded in confined spaces for up to 2 years with minimal protection and poor ventilation. Neurological, neuropsychological, neurophysiological, and pulmonary examinations were given to 49 welders. Clinical cases were selected on the basis of apriori defined criteria pertaining to welding history and neurological/neuropsychological features. Among the 43 eligible welders, 11 cases of manganism were identified presenting with the following symptoms: sleep disturbance, mood changes, bradykinesia, headaches, sexual dysfunction, olfaction loss, muscular rigidity, tremors, hallucinations, slurred speech, postural instability, monotonous voice, and facial masking. Significant associations between outcome variables and cumulative exposure index (CEI) or blood Mn (MnB) were obtained with CEI for variables implicating attention and concentration, working and immediate memory, cognitive flexibility, and verbal learning; and with MnB for executive function, cognitive flexibility, visuo-spatial construction ability, and visual contrast sensitivity. This study strongly suggests that neuropsychological features contribute in a dose-effect related way to the portrait of manganism usually characterized by tremor, loss in balance, diminished cognitive performance, and signs and symptoms of parkinsonism.

A woman, aged 27 years, developed acute headache and fever followed by tremor, rigidity, and bradykinesia. Masked face, drooling saliva, monotonous voice, and dysphagia were observed. She was totally bedridden during the worst period because of marked generalized rigidity and bradykinesia. There was no neurological disturbance other than parkinsonism. Several herpetic vesicles were noticed at the left angle of her mouth. The cerebrospinal fluid revealed a mononuclear pleocytosis with a normal concentration of sugar and protein. The antibody test for Type I herpes simplex virus was positive in the serum but negative in the cerebrospinal fluid. Brain CT and EEG were normal. However, MRI study showed markedly increased signals in the bilateral substantia nigra on T2-weighted, proton density, and in gradient recall acquisition imagings. Those abnormal findings had almost disappeared in a follow-up MRI study 2 months later. Her parkinsonian symptoms were substantially resolved by the time. However, PET scans, performed 8 months later, disclosed: (1) mild reduction of fluorodopa uptake; and (2) increased raclopride binding, predominantly in the putamen. These findings suggest a subclinical nigrostriatal dopaminergic deficit and a relative excess of the D2 receptors, with a pattern similar to that found in typical idiopathic parkinsonism.

Headache makes one of the most common side effects of frequently pesticide application. This is to be taken care of in rural areas. Headaches have been reported with the use of ivermectin, ivermectin-diethylcarbamazine, organophosphates, and also with the fungicide maneb and copper sulfate, carbofuran, hexonal, dioxin, methomyl and its salts, as well as rare cases of poisoning with the fungicide combination of propineb and cymoxanil. Headache often occurs after long term work with pesticides and/or in laboratories. There are numerous symptoms accompanying headache in pesticide poisoning the most common being elevated body temperature, lassitude, dizziness, irritability, nausea, vomiting, epigastric pain, diarrhea, myalgia, pains in the arms and legs, sleepiness, pains in joints, irritation of eyes/face/skin, sweating. Much less common are respiratory disturbances, tachycardia, tachypnea and other cardiac distur bances, fall of blood pressure, gastrointestinal discomforts, constipation, poor appetite, significant decrease in leukocyte count, anemia, albuminuria, azotemia, fasciculations, miosis, blurred vision, memory disturbances and other neurologic disturbances, postural tremor, signs of cerebral function damage, bradykinesia, etc.

Deep brain stimulation (DBS) has developed during the past 20 years as a remarkable treatment option for several different disorders. Advances in technology and surgical techniques have essentially replaced ablative procedures for most of these conditions. Stimulation of the ventralis intermedius nucleus of the thalamus has clearly been shown to markedly improve tremor control in patients with essential tremor and tremor related to Parkinson disease. Symptoms of bradykinesia, tremor, gait disturbance, and rigidity can be significantly improved in patients with Parkinson disease. Because of these improvements, a decrease in medication can be instrumental in reducing the disabling features of dyskinesias in such patients. Primary dystonia has been shown to respond well to DBS of the globus pallidus internus. The success of these procedures has led to application of these techniques to multiple other debilitating conditions such as neuropsychiatric disorders, intractable pain, epilepsy, camptocormia, headache, restless legs syndrome, and Alzheimer disease. The literature analysis was performed using a MEDLINE search from 1980 through 2010 with the term deep brain stimulation, and several double-blind and larger case series were chosen for inclusion in this review. The exact mechanism of DBS is not fully understood. This review summarizes many of the current and potential future clinical applications of this technology.
