Cranial neuroimaging in infantile tremor syndrome (ITS).

MR imaging of acquired hepatocerebral degeneration.

Acquired hepatocerebral degeneration is a well-known irreversible neurologic syndrome that occurs occasionally in patients who have chronic liver disease and portocaval shunting (1, 2]. Affected patients have some combination of coarse postural and action tremor, dyskinesias of cranial predominance, dysarthria, gait and limb ataxia, and variable impairment of intellectual function (1, 2). Few n...

Neuroimaging in Fragile X-Associated Tremor/Ataxia Syndrome (FXTAS)

Movement Disorders Following Cerebrovascular Lesions in Cerebellar Circuits

Cerebellar circuitry is important to controlling and modifying motor activity. It conducts the coordination and correction of errors in muscle contractions during active movements. Therefore, cerebrovascular lesions of the cerebellum or its pathways can cause diverse movement disorders, such as action tremor, Holmes' tremor, palatal tremor, asterixis, and dystonia. The pathophysiology of abnorm...

Infantile spasms.

Infantile spasms constitute both a distinctive seizure type and an age-specific epilepsy syndrome that have been extensively described for over a century. Standardization of the classification of infantile spasms has evolved, culminating in recent recommendations for separately recognizing and distinguishing the seizure type (spasms or epileptic spasms) and the epilepsy syndrome of infantile sp...

Infantile tremor syndrome: A review and critical appraisal of its etiology

Infantile tremor syndrome (ITS) is defined by the tetrad of pallor, developmental delay/regression, skin pigmentation, and brown scanty scalp hair. Involuntary movements in the form of tremors supervene in the natural course of the illness in a significant number of cases. The disorder occurs in exclusively breast-fed infants of vegetarian mothers belonging to economically deprived sections of ...
