Aicardi syndrome is a very rare neurological condition due to a congenital abnormality of brain development.
A syndrome characterized by a silent and inert state without voluntary motor activity despite preserved sensorimotor pathways and vigilance.
A syndrome characterized by a transient loss of the ability to form new memories. It primarily occurs in middle aged or elderly individuals, and episodes may last from minutes to hours.
An autosomal recessive disorder characterized by retinitis pigmentosa; polydactyly; obesity; mental retardation; hypogenitalism; renal dysplasia; and short stature.
The basal ganglia consists of masses of subcortical grey matter deep within the cerebral hemispheres. Along with the cerebellum, the basal ganglia controls movement and posture, adjusting the body to do certain things, as well as inhibits unwanted movement. Lesions in the basal ganglia cause disturbances in motor activity. Information is sent from the motor cortex to the basal ganglia and is relayed back via the thalamus. Recent studies suggest that the basal ganglia contains five segregated circuits for different functions of behavior. Each involves separate regions within the basal ganglia and the thalamus.
Diseases that affect the structure or function of the cerebellum. Cardinal manifestations of cerebellar dysfunction include dysmetria, gait ataxia, and muscle hypotonia.
A localized cavity filled with pus secondary to a bacterial infection.
Increased intracellular or extracellular fluid in brain tissue.
A condition characterized by long-standing brain dysfunction or damage, usually of three months duration or longer.
Corticobasal degeneration is a progressive neurological disorder characterized by nerve cell loss and atrophy (shrinkage) of multiple areas of the brain including the cerebral cortex and the basal ganglia.
An autosomal recessively inherited glycogen storage disease caused by glucan 1,4-Alpa-Glucosidase Definciency. Large amounts of glycogen accumulate in the lysomes of skeletal muscle ( muscle, skeletal); heart; liver; spinal cord; and brain.

This category contains sites about the rare Neurological Condition called Intracranial Hypertension (also known as Pseudotumor Cerebri, Benign Intracranial Hypertension and Idiopathic Intracranial Hypertension).
Sites submitted should contain information regarding Intracranial Hypertension and its diagnosis, treatment options, and personal experiences.
A rare, genetic disorder that affects the area of the brain that controls balance and coordination.
A fatal genetic disorder of the nervous system that cripples and paralyzes while leaving the intellect intact.
A variant of the GUILLAIN-BARRE SYNDROME characterized by the acute onset of oculomotor dysfunction, ataxia, and loss of deep tendon reflexes with relative sparing of strength in the extremities and trunk.
Olivopontocerebellar atrophy (OPCA) refers to a group of ataxias characterized by progressive neurological degeneration affecting the cerebellum, the pons and the inferior olives.
PEHO syndrome (Progressive encephalopathy with Edema, Hypsarrhythmia, and Optic atrophy) is an autosomal recessive disorder leading to profound psychomotor retardation. The etiology and pathogenesis of the syndrome are unknown. The main clinical findings are severe hypotonia, brisk reflexes, convulsions, profound psychomotor retardation, subcutaneous edema, and absence or early loss of visual fixation. The nature of the syndrome is progressive and most patients die before the age of 15 years.
Schizencephaly is an extremely rare developmental disorder characterized by abnormal slits, or clefts, in the brain's cerebral hemispheres.
