Overview Huntington’s disease (HD) is a rare genetic disorder that causes the progressive breakdown of nerve cells in the brain. It is also known as Huntington’s chorea because one of the most characteristic symptoms of the disease is involuntary movements, or chorea. HD is caused by a mutation in the huntingtin (HTT) gene, which provides…
What is traumatic vision syndrome? Post-traumatic vision syndrome is a disruption of the visual process. Post-traumatic vision syndrome becomes after traumatic brain injury. This disruption is affected by the neurologic system of the extraocular muscles that control eye movements. Sign and Symptoms of post-traumatic vision syndrome: Visual dysfunction clinical signs of post-traumatic vision syndrome: Non-visual…
What is Pickwickian syndrome? Pickwickian syndrome is characterized by a combination of obesity, sleep apnea, and hypoventilation (abnormally low levels of oxygen and high levels of carbon dioxide in the blood. People with Pickwickian syndrome typically have a higher risk of developing serious health problems such as heart disease, diabetes, and high blood pressure. Treatment…
What is Hydrocephalus? Hydrocephalus is a condition in which extra cerebrospinal fluid (CSF) accumulates within the brain’s fluid-containing cavities or ventricles. The term hydrocephalus is derived from the Greek words hydro, which means water, and cephalus, which means head. Although the term translates as “water on the brain,” it refers to the accumulation of cerebrospinal…
What is a Brain aneurysm? A brain aneurysm, also known as a cerebral aneurysm, is a bulge in a weak region of an artery in or around your brain. The constant pressure of blood flow pushes the weakened area outward, forming a blister-like bump. When blood flows into this bulge, the aneurysm stretches even distant….
What is Central Pain Syndrome? Central pain syndrome is a neurological disease caused by injury to or dysfunction of the central nervous system (CNS). The CNS contains the brainstem, brain, and spinal cord. This syndrome can be generated by: The pain associated with central pain syndrome varies widely among persons partially because of the variety…
What is Basilar Artery Thrombosis? Basilar artery thrombosis is a devastating stroke condition with a high morbidity and mortality rate. Its initial presentation is frequently nonspecific and may include dizziness or blurred vision. Bilateral vertebral artery joint at the junction of the pons-medulla formed the Basilar artery. It delivers oxygen-rich blood to the brain’s brainstem,…
What is Myasthenia Gravis? Myasthenia gravis (MG) is an autoimmune condition, which means that the body’s immune system incorrectly attacks its parts. MG interrupts the communication between nerves and muscles (the neuromuscular junction). Myasthenia gravis (MG) patients are unable to actively control their muscles. They experience varying degrees of fatigue and muscular weakness. The muscles…
What is Rett syndrome? Rett syndrome is a genetic neurological and developmental disorder that affects to depends on the way the brain develops. Rett syndrome is mainly affected mainly females and rare cases affected males. In most cases, babies with Rett syndrome are seen to develop expected for the first six months of the born….
What is Diastematomyelia? Diastematomyelia, also called a split cord malformation, leads to a variety of spinal dysraphism (spina bifida occulta) when there is a longitudinal separation in the spinal cord. Women are involved much more generally than men. This disease happens in the presence of a cartilaginous, osseous, or fibrous septum in the central part…
