Dementia

Dementia is the name for a group of symptoms caused by disorders that affect the brain. It is not a specific disease. People with dementia may not be able to think well enough to do normal activities, such as getting dressed or eating. They may lose their ability to solve problems or control their emotions. Their personalities may change. They may become agitated or see things that are not there. . Memory loss is a common symptom of dementia. However, memory loss by itself does not mean you have dementia. People with dementia have serious problems with two or more brain functions, such as memory and language. Although dementia is common in very elderly people, it is not part of normal aging. Many different diseases can cause dementia, including Alzheimer's disease and stroke. Drugs are available to treat some of these diseases. While these drugs cannot cure dementia or repair brain damage, they may improve symptoms or slow down the disease.

Alzheimer disease

Alzheimer disease (AD) is characterized by dementia that typically begins with subtle and poorly recognized failure of memory and slowly becomes more severe and, eventually, incapacitating. Other common findings include confusion, poor judgment, language disturbance, agitation, withdrawal, and hallucinations. Occasionally, seizures, Parkinsonian features, increased muscle tone, myoclonus, incontinence, and mutism occur. Death usually results from general inanition, malnutrition, and pneumonia. The typical clinical duration of the disease is eight to ten years, with a range from one to 25 years. Approximately 25% of all AD is familial (i.e., =2 persons in a family have AD) of which approximately 95% is late onset (age >60-65 years) and 5% is early onset (age <65 years). [from GeneReviews]

Mental disorder

Mental disorders include a wide range of problems, including. -Anxiety disorders, including panic disorder, obsessive-compulsive disorder, post-traumatic stress disorder, and phobias. -Bipolar disorder. -Depression. -Mood disorders. -Personality disorders. -Psychotic disorders, including schizophrenia. There are many causes of mental disorders. Your genes and family history may play a role. Your life experiences, such as stress or a history of abuse, may also matter. Biological factors can also be part of the cause. A traumatic brain injury can lead to a mental disorder. A mother's exposure to viruses or toxic chemicals while pregnant may play a part. Other factors may increase your risk, such as use of illegal drugs or having a serious medical condition like cancer. Medications and counseling can help many mental disorders. .  [from MedlinePlus]

Lewy body dementia

Dementia with Lewy bodies (DLB) is a neurodegenerative disorder clinically characterized by dementia and parkinsonism, often with fluctuating cognitive function, visual hallucinations, falls, syncopal episodes, and sensitivity to neuroleptic medication. Pathologically, Lewy bodies are present in a pattern more widespread than usually observed in Parkinson disease (see PD; 168600). Alzheimer disease (AD; 104300)-associated pathology and spongiform changes may also be seen (McKeith et al., 1996; Mizutani, 2000; McKeith et al., 2005). [from OMIM]

Tauopathies

Neurodegenerative disorders involving deposition of abnormal tau protein isoforms (TAU PROTEINS) in neurons and glial cells in the brain. Pathological aggregations of tau proteins are associated with mutation of the tau gene on chromosome 17 in patients with ALZHEIMER DISEASE; DEMENTIA; PARKINSONIAN DISORDERS; progressive supranuclear palsy (SUPRANUCLEAR PALSY, PROGRESSIVE); and corticobasal degeneration. [from MeSH]

Vascular disorder

The vascular system is the body's network of blood vessels. It includes the arteries, veins and capillaries that carry blood to and from the heart. Problems of the vascular system are common and can be serious. Arteries can become thick and stiff, a problem called atherosclerosis. Blood clots can clog vessels and block blood flow to the heart or brain. Weakened blood vessels can burst, causing bleeding inside the body. . You are more likely to have vascular disease as you get older. Other factors that make vascular disease more likely include. - Family history of vascular or heart diseases. - Pregnancy. - Illness or injury . - Long periods of sitting or standing still. - Any condition that affects the heart and blood vessels, such as diabetes or high cholesterol . - Smoking . - Obesity . Losing weight, eating healthy foods, being active and not smoking can help vascular disease. Other treatments include medicines and surgery.  [from MedlinePlus]

Movement disorders

Imagine if parts of your body moved when you didn't want them to. If you have a movement disorder, you experience these kinds of impaired movement. Dyskinesia is abnormal uncontrolled movement and is a common symptom of many movement disorders. Tremors are a type of dyskinesia. . Nerve diseases cause many movement disorders, such as Parkinson's disease. Other causes include injuries, autoimmune diseases, infections and certain medicines. Many movement disorders are inherited, which means they run in families. Treatment varies by disorder. Medicine can cure some disorders. Others get better when an underlying disease is treated. Often, however, there is no cure. In that case, the goal of treatment is to improve symptoms and relieve pain.  [from MedlinePlus]
