Ataxia Telangiectasia Brain And Nerves
The substantia nigra: Parkinson's disease destroys the dopaminergic neurons that live in a part of the midbrain called the substantia nigra (dark substance). The loss of Dopamine causes the basal ganglia to malfunction and this causes the slowness, tremor and dementia. ...Read moreSee 1 more doctor answer
The brain and spinal cord communicates with what is occurring in the internal organs and limbs by nerve fibers where are like electrical wires with insulation (myelin) and the "copper" (axon). Within brain and spinal cord these nerves connect to other nerves via synapses on both axons and dendrites. A nerve can carry information regarding sensations, and ...Read more
Prion: Prions are proteins that have changed conformation, so that the normal function of the protein inside the cells won't work. The prions' also causes other normal proteins to misfold and make more prions, spreading the process. The prions affect many cells in the body, but they particularly harm nerve cells in the brain, causing progressive rapid degeneration. They are not alive, and have no dna. ...Read more

Dementia: Frontal lobe cause blunting. Parietal lobe cause auditory hallucinations. Temporal lobe cause disturbed emotions. Occipital lobe cause visual hallucinations. ...Read more

Ataxia: Cerebellar degneration means that the part of the brain that controlls coordination and balance is losing cells and likely getting smaller. Ataxia is the clumsiness, imbalance, slurred speech and/or abnormal eye movements that can accompany cerebellar degeneration. A paraneoplastic cerebellar syndrome is when the body's immune response to cancer somewhere else damages the cerebellum "by mistake". ...Read more
Hemorrhage: Most of the damage of an arteriovenous malformation occurs when the blood vessel or vessels are spontaneously ruptured and bleed into the brain, causing pressure and damage to the brain. The same can occur with an av malformation in the brain stem or spine. ...Read moreSee 1 more doctor answer

Mixed motor sensory peripheral neuropathy in both legs. ncs also found ulnar neuropathy both elbows. what disease can cause this?
An approach: We approach peripheral neuropathy etiology by blood and urine testing, but can focus our tests based on whether this is an axonal or Schwann cell involvement, which your EMG-NCS should have indicated if done properly. Most common causes in USA are diabetes, and nutritional deficiency, associated with alcohol. Worldwide, may well be leprosy or HIV. ?Concierge? ...Read more
Injury location: Although specific sensory branches go to skin and motor branches go to muscle, the main nerve trunks contain both. These large cables split off smaller branches that contain only sensory or motor nerve cells. If an injury occurs on the skin, sensantion nearby is affected. If a small motor nerve is injured, nearby muscles are paralyzed. But if a large nerve is injured, both can occur. ...Read moreSee 1 more doctor answer
Could MS located in the spine cause symptoms primarily impairing brain function? Like lightheadedness (brain fog) and bad short term memory?
Not related to MS: MS in the spine wouldn't cause any issues with brain function. MS taking place in the brain could cause some issues with lightheadedness but not memory issues, it would have to be a very end-stage degenerative MS to cause such symptoms and even then it would likely be a secondary cause, not a primary. Other things such as vertigo, viral infections, stress, sleep etc could be benign causes of this ...Read more

Numbness, postural tremors weakness fatigue. Is this multiple sclerosis? Mri of brain and spine normal, hyperreflexia. Low B12 and sjogren's syndrome.
Explanation: You mention two issues, and at age 23, am surprised at this combination, but b-12 deficiency can result in peripheral nerve and spinal cord problems which may explain many of your symptoms. Sjogren's can mimic ms and also cause a small fibre neuropathy which could explain additional issues. Do not need an ms explanation here, as doubtful you have that also. Suggest neurology eval. ...Read more

Brain: Stroke is a condition that primarily affects the brain.There are ischemic strokes where a particular blood vessel is blocked and the part of the brain that is perfused is deprived of blood/oxygen and then dies.There are hemorrhagic strokes where there is the accumulation of blood in the brain (intracerebral hemorrhage)or aneuysmal bleed where the blood spills out into the outer layers of the brain. ...Read moreSee 2 more doctor answers
Varies: The primary systems involved in CP are the muscles and nervous involved in movement and maintaining posture. Abnormally high or low muscle tone and impairments in the control of these muscle are the hallmark of cp.Other systems can have associated problems, like seizures, visual defects and more. This is a broad diagnosis that varies from very mild to quite disabling, so its features also vary. ...Read more
Ataxia means movements without coordination. People with ataxia have incoordination because the parts of the nervous system that control movement and balance are not working properly. Ataxia can be associated with infections, injuries, or degenerative changes in the central nervous system. Ataxias may be hereditary ...Read more
