It may be caused by hypovolemia a decreased amount of blood in the body , resulting from the excessive use of diuretics, vasodilators, or other types of drugs, dehydration, or prolonged bed rest. Diagnosis requires brain scans and lumbar puncture. These nerves provide movement and feeling to the arm, hand, and fingers. Other symptoms may include visual agnosia inability to visually recognize objects , loss of normal fear and anger responses, memory loss, distractibility, seizures, and dementia. Onset is in childhood or early adolescence. Symptoms may include large, low-set ears, small eyes, microcephaly abnormal smallness of the head , micrognathia abnormal smallness of the jaws , clenched fists, wide-set nipples, vision impairments, involuntary eye movements, and mental retardation, which can be moderate or severe. Under ordinary circumstances, the symptoms can easily be relieved within a day a two, but repeated incidences of brain concussions can even lead to permanent brain damage.
Neurological symptoms may include motor weakness, startle reaction to sound, early blindness, progressive mental and motor deterioration, macrocephaly an abnormally enlarged head , cherry-red spots in the eyes, seizures, and myoclonus shock-like contractions of a muscle. Symptoms of the disorder may include deterioration of motor function, pychosis dementia, seizures, headache, dysarthria poorly articulated speech , spasticity stiffness of the limbs and spastic paralysis, eye impairments, and athetosis involuntary, writhing movements. Levine-Critchley Syndrome - very rare inherited disorder mainly involving progressive muscle weakness and wasting, abnormal limb movement, progressive cognitive loss and red blood cell abnormalities. The deterioration may also affect the tongue, the soft and fleshy part of the roof of the mouth, and the gums. Slow, but progressive muscle weakness starts in the proximal muscles muscles closest to the trunk of the body which eventually leads to difficulties climbing stairs, rising from a sitting position, lifting objects, or reaching overhead. Central pain syndrome may affect a large portion of the body or may be more restricted to specific areas, such as hands or feet.
Parts of the brain that can be damaged include the cerebral hemispheres, cerebellum, and brain stem. The prognosis for otherwise normal development is excellent in most cases. Other types of defects of the brain such as , small brain ; enlarged ventricles; or porencephalic cysts a gap in the brain where there should be healthy brain tissue. This is because a child is dependent on parents and caregivers for emotional and other development. When you go above the sea level, you gradually experience decreased or insufficient oxygen pressure at the height of about 8,000 feet or more. Sleep deprivation, chronic stress along with psychiatric disorders like panic attacks or multiple personality disorders can lead to sleepwalking disorder.
As children get older, lack of facial expression and inability to smile become the dominant visible symptoms. Investigators now believe that migraine is caused by inherited abnormalities in genes that control the activities of certain cell populations in the brain. Dentatorubral Atrophy - Dentatorubral pallidoluysian atrophy is a rare neurodegenerative disorder characterized by cerebellar ataxia, myoclonic epilepsy, choreoathetosis, and dementia. It begins late in the fourth decade of life and increases in severity with age. This syndrome may occur in individuals who have damage to the corpus callosum, which connects the two cerebral hemispheres of the brain. The disorder is characterized by absence or underdevelopment of the cerebellar vermis and a malformed brain stem molar tooth sign. Infantile Refsum Disease - is a disorder characterized by the reduction or absence of peroxisomes in the body and by the accumulation of phytanic acid in blood plasma and tissue.
Although inflammation may also affect the brain, the lesions are different to those observed in the related condition multiple sclerosis. Diseases and Disorders Very rarely do people, other than those involved in the medical field, bother to find out anything much about different diseases and disorders, until somebody close is afflicted by them. Substance-related disorders are those that involve the use and abuse of different substances such as cocaine, methamphetamine, opiates, and alcohol. Unable to recall the past, the person connects totally with the new identity while totally relinquishing the memories of the former identity. Due to this abnormal cellular development, the vessels may become stenosed. Symptoms can appear gradually or all at once, and also may include uncoordinated movements, muscular weakness, stumbling and falling, slurred speech, difficulty concentrating and writing, and emotional instability. When the person has a manic episode he or she may feel extremely happy or be in an irritable and jumpy mood.
They result from degeneration of the lateral corticospinal tracts in the spinal cord. The main features of Korsakoff's amnesic syndrome are the impairments in acquiring new information or establishing new memories, and in retrieving previous memories. Agenesis of the corpus callosum occurs when the corpus callosum, the band of tissue connecting the two hemispheres of the brain, does not develop typically in utero. Fahr's Syndrome - also known as Idiopathic Basal Ganglia Calcification or Fahr's Syndrome is a rare, genetically dominant, inherited neurological disorder characterized by abnormal deposits of calcium in areas of the brain that control movement, including the basal ganglia and the cerebral cortex. Common medical conditions that are covered include communicable and infectious diseases, common medical illnesses and injuries, mental disorders, genetic disorders, skin diseases, blood disorders, lung diseases, metabolic diseases, and various other health disorders.
The broadest division is between central nervous system disorders and peripheral nervous system disorders. Almost 7 percent of American adults had at least one major depressive episode in the past year, and more than 18 percent experienced an anxiety disorder. The cause of brain tumors is largely unknown. They generally display a lack of emotional expression and can appear cold and aloof. It can affect fetuses or newborns; premature babies are at the greatest risk of the disorder.
Characteristic facial features may include an underdeveloped upper jaw bone maxillary hypoplasia , a broad nose, protruding nostrils nares , an abnormally prominent brow, down-slanting eyelid folds palpebral fissures , widely spaced eyes hypertelorism , large ears, and unusually thick eyebrows. Sometimes mental disorders can be trauma-induced. It controls thoughts, memory, speech, and movement. Patients have severe mental and physical problems throughout life. Other disorders, like neurodegenerative diseases and some traumatic brain injuries, have no cure. The treatment usually involves bed rest under observation for about 24 hours, but severe headache can be relieved by the prescription of ibuprofen or acetaminophen, and the use of aspirin has to be avoided because it may lead to internal bleeding.
