Alzheimer's disease is the most common cause of dementia. Currently, although the causes of Alzheimer's disease are largely unknown, experts know that a small percentage are linked to mutations in three genes, which can be passed from parent to child. While a number of different genes may be associated with Alzheimer's disease, one important gene that increases the risk is apolipoprotein E4 (APOE). Patients with Alzheimer's disease have plaques and tangles in the brain. Plaques are clumps of a protein called beta-amyloid and tangles are fibrous tangles made up of the protein Tau. It's thought that these clumps damage healthy nerve cells and the fibers that connect them. Other genetic factors can make people more likely to develop Alzheimer's disease. Vascular dementia. This second most common type of dementia is caused by damage to the vessels that supply blood to the patient's brain. Blood vessel problems can cause strokes or damage the brain in different ways, such as damaging fibers in the brain's white matter. The most common symptoms of Vascular Dementia include difficulty solving problems, slow thinking, concentration and organization. These trends are more notable than memory loss. Lewy body dementia. Lewy body dementia is an abnormal, balloon-shaped mass of protein found in the brains of people with Lewy body dementias such as Alzheimer's disease and Parkinson's disease. This is one of the more common progressive dementia disorders. Common signs and symptoms include behavior during sleep dreams, seeing things that are not real (also known as visual hallucinations), and problems with focus and attention. Other signs include uncoordinated or slow movement, tremors, and rigidity (parkinsonism). Frontotemporal dementia. This is a group of diseases characterized by the breakdown (degeneration) of nerve cells and their connections in the frontal and temporal lobes of the brain, areas often associated with personality, behavior and language. language. Common symptoms affect behavior, personality, thinking, judgment, and language and movement. Mixed Dementia. Autopsy studies of the brains of people 80 and older with dementia found that many had a combination of several causes, such as Alzheimer's disease, vascular dementia, and dementia. Lewy body intelligence. Studies are underway to determine how mixed dementia affects symptoms and treatments. Other disorders related to dementia Huntington's disease is known to be a genetic disease that affects nerve cells in the brain. Brain damage tends to become more severe and can affect movement, cognition and behavior and usually appears around age 30 or 40. Traumatic brain injury. This condition is often caused by repetitive head trauma such as boxers, football players or soldiers. Depending on the part of the brain damaged, this condition can cause signs and symptoms of dementia such as depression, outbursts, memory loss and impaired speech. In addition, traumatic brain injury can also cause parkinsonism, symptoms of which may not appear until years after the injury. Creutzfeldt-Jakob Disease (Mad Cow Disease; CJD: Cerebral Palsy). Signs and symptoms of this disease usually appear after age 60. Parkinson disease. Many people with Parkinson's disease eventually develop symptoms of dementia (Parkinson's disease dementia). The dementia-like condition can be reversed Some causes of dementia or dementia-like symptoms can be reversed with treatment such as: Infections and immune disorders. Dementia-like symptoms may be due to fever or other side effects of the body's attempt to fight infection. Multiple sclerosis (Multiple Sclerosis) and other conditions where the body's immune system attacks nerve cells can also cause dementia. Subdural hematoma. Bleeding between the surface of the brain and the meninges, common in the elderly after a fall, can cause symptoms similar to those of dementia. Poisoning. Exposure to heavy metals, such as lead and other toxins, pesticides, psychotropic drugs, or heavy alcohol use can lead to symptoms of dementia. Symptoms may resolve with treatment. Brain tumors. Rarely, dementia can occur due to damage caused by a brain tumor. Anoxia. This condition, also known as hypoxia, occurs when organ tissues do not receive enough oxygen. Anoxia can occur due to apnea due to asthma, heart attack, carbon monoxide poisoning, or other causes.
