A 50-year-old man presented with neuro-Behçet's disease (NBD) manifesting as a large neoplasm-like lesion affecting the brainstem, basal ganglia, and white matter of the cerebral hemisphere. He had no history of disease except for psychoneurosis. On admission, neurological examination found left hemiparesis and dysarthria. Magnetic resonance (MR) imaging showed multiple small ring-like enhancem...

introduction:dystonia is a disorder of movement caused by various etiologies. laryngeal dystonia is caused by the spasm of laryngeal muscles. it is a disorder caused by vocal fold movement in which excessive adduction or abduction of the vocal folds occurs during speech. the pathophysiology of this type of dystonia is not fully known. some researchers have suggested that basal ganglia structure...

fahr’s disease is a progressive and idiopathic basal ganglia calcification with normal metabolism of calcium and phosphor with motor and psychiatric signs and symptoms. dementia, chorea attetosise, psychosis and depression due to fahr’s disease are frequently reported, but fahr,s disease with bipolar mood disorder manifestation is very rare and we found only 3 case in review of literature from ...

Infantile spasms associated with brain tumors have been reported. A focal cortical lesion can induce infantile spasms by triggering the brainstem and basal ganglia in this vulnerable age group. We report the case of a female infant with a low-grade glioma in the right basal ganglia, spreading to the cortical area. She presented at the age of five months with left hemiparesis and partial seizure...

Successful remembering involves both hindering irrelevant information from entering working memory (WM) and actively maintaining relevant information online. Using a voxelwise lesion-behavior brain mapping approach in stroke patients, we observed that lesions of the left basal ganglia render WM susceptible to irrelevant information. Lesions of the right prefrontal cortex on the other hand make ...

Uremic encephalopathy is a well-known disease with typical MR findings including bilateral vasogenic or cytotoxic edema at the cerebral cortex or basal ganglia. Involvement of the basal ganglia has been very rarely reported, typically occurring in uremic-diabetic patients. We recently treated a patient who had non-diabetic uremic encephalopathy with an atypical lesion distribution involving the...

Previous publications have discussed the occurrence of intracerebral hemorrhages, hallucinations and psychosis in COVID-19 patients. In this article, we reviewed literature on subject while depicting case a 63-year-old female patient who suffered from an hemorrhage right basal ganglia thalamus two weeks after diagnosis developed visual hallucinosis shortly after. We concluded that, there may be...

Transient memory impairment can be occurred by many causes. One of them is acute focal brain lesion in strategic site. Caudate nucleus and medial basal ganglia (globus pallidus) are lesion of strategic site. They play its role in cognitive processing. But lateral basal ganglia (putamen) is known as a structure involving movement, not cognitive function. We report a interesting case of transient...

Although the mammalian basal ganglia have long been implicated in motor behavior, it is generally recognized that the behavioral functions of this subcortical group of structures are not exclusively motoric in nature. Extensive evidence now indicates a role for the basal ganglia, in particular the dorsal striatum, in learning and memory. One prominent hypothesis is that this brain region mediat...
