Magnetic resonance imaging (MRI) of the brain of ZTTK syndrome patients have revealed significant abnormalities. [ 1 ] Abnormal gyration patterns were seen, including polymicrogyria ; many unusually small folds in the brain, simplified gyria; reduced number and shallow appearance of gyri, and periventricular nodular heterotopia; failure of ...
This sign is also sometimes seen as part of a "discontinuation syndrome" associated with certain psychotropic medications, such as selective serotonin reuptake inhibitors and serotonin norepinephrine reuptake inhibitors, particularly paroxetine and venlafaxine. Typically, it only occurs after having taken the medication for some duration, and ...
AHC patients exhibit a wide range of symptoms in addition to hemiplegic attacks. [1] These can be further characterized as paroxysmal and non-paroxysmal symptoms. Paroxysmal symptoms are generally associated with hemiplegic attacks and may occur suddenly with hemiplegia or on their own.
CRPS-RSD of the left foot imaged with medical thermology during a cold pressor test. Examples of neuro-musculoskeletal indications for medical thermology include Reflex Sympathetic Dystrophy (RSD), Chronic Regional Pain Syndrome (CRPS), Dysautonomia , Migraine , Fibromyalgia (and other weather-sensitive pain syndromes), thoracic outlet syndrome ...
It was originally thought [5] that raised CSF protein without pleocytosis ('albuminocytological dissociation') was a characteristic feature, as it is in Guillain–Barré syndrome, but this has not been supported in more recent work. [7] In only 30% of cases is an MRI brain scan abnormal. Nerve conduction studies may show an axonal ...
The tests most commonly used for neuropsychological testing include WAIS-III, Stroop test, Bourdon Wiersma test, and the Rey–Osterrieth complex figure test. These tests allow physicians to evaluate the degree to which the bilateral lesions in the operculum have been affected, and allow for the determination of proper treatment.
Resting state fMRI (rs-fMRI or R-fMRI), also referred to as task-independent fMRI or task-free fMRI, is a method of functional magnetic resonance imaging (fMRI) that is used in brain mapping to evaluate regional interactions that occur in a resting or task-negative state, when an explicit task is not being performed.
Pantothenate kinase-associated neurodegeneration (PKAN), formerly called Hallervorden–Spatz syndrome, [1] is a genetic degenerative disease of the brain that can lead to parkinsonism, dystonia, dementia, and ultimately death. Neurodegeneration in PKAN is accompanied by an excess of iron that progressively builds up in the brain.
