Department of Neurology, Chang Gung Medical College and Memorial Hospital, Taipei, Taiwan.

Computerized EEG spectral analysis and topographic mapping were performed on 14 patients with Wilson's disease (WD) and 10 normal subjects of comparable ages. The predominant EEG changes in WD were diffuse but uneven topographic abnormalities with a decrease in alpha activity, an increase in theta and delta activities, and a low voltage background mainly in the alpha frequency band. Eleven patients (80%) had at least one of the above EEG changes. Furthermore, topographic mapping provided more clearly defined foci of slowing and epileptiform activity. Patients with cerebral white matter involvement, akinetic-rigid syndrome, dystonia, or psychiatric symptoms tended to have more abnormal EEGs. It is concluded that EEG changes in WD are common and the quantitative EEG analysis can increase the likelihood of detecting mild or even subtle EEG abnormalities in individual patients as well as in the patient group.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D001921	Brain	The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.	Encephalon
D001931	Brain Mapping	Imaging techniques used to colocalize sites of brain functions or physiological activity with brain structures.

D004569	Electroencephalography	Recording of electric currents developed in the brain by means of electrodes applied to the scalp, to the surface of the brain, or placed within the substance of the brain.	EEG,Electroencephalogram,Electroencephalograms
D004827	Epilepsy	A disorder characterized by recurrent episodes of paroxysmal brain dysfunction due to a sudden, disorderly, and excessive neuronal discharge. Epilepsy classification systems are generally based upon: (1) clinical features of the seizure episodes (e.g., motor seizure), (2) etiology (e.g., post-traumatic), (3) anatomic site of seizure origin (e.g., frontal lobe seizure), (4) tendency to spread to other structures in the brain, and (5) temporal patterns (e.g., nocturnal epilepsy).

D006527	Hepatolenticular Degeneration	A rare autosomal recessive disease characterized by the deposition of copper in the BRAIN; LIVER; CORNEA; and other organs. It is caused by defects in the ATP7B gene encoding copper-transporting ATPase 2 (EC 3.6.3.4), also known as the Wilson disease protein. The overload of copper inevitably leads to progressive liver and neurological dysfunction such as LIVER CIRRHOSIS; TREMOR; ATAXIA and intellectual deterioration. Hepatic dysfunction may precede neurologic dysfunction by several years.
