What are different types of brain changes?
brain changes is not a technical term with a specific link. As such, it can refer to negative changes in the brain, such as atrophy, dementia, strokes, seizures and tumors, and all the effects they cause. However, it may also apply to positive changes in the brain, such as learning, creating memories and normal development.
Positive changes in the brain are part of the normal development of human beings. Although the nerve plate - the first step in the formation of nervous and brain production - on the day of the day of the development of the embryo does not reach the maximum weight up to the age of 19-21. There is a change during this time. The term neuroplasticity captures the fact that learning and remembering results in physical change in the brain. New nerve pathways can be created and other synapses may be created between neurons. This means learning and forming memories causes physical changes in the brain.
Negative brain changes may be the result of aging, injury or illness. Aging brings synaptic pruning, eliminating weaker withynaptic connections and death of neurons that are not involved in receiving or transmitting information. Neuroinflammation is also associated with aging, regardless of the disease, but it is also a physiological change in the brain, which is bound to specific neurological problems such as stroke, multiple sclerosis, meningitis and brain trauma.
dementia - which can be caused by a number of different things such as Alzheimer's disease, Parkinson/Lew body, stroke, head injury, multiple sclerosis, alcoholism, syphilis, neuroaids, chronic hypothyroidism, Huntington's disease or vitamin B12 deficiency. This is characterized by a number of brain changes, such as beta-amyloid plaques, neurofibrillary tangles and brain atrophy in most people. In January 2009, a new study showed that the brains of people who have diabetes and develop dementia such as Alzheimer's disease differ from people Be peopleFrom diabetes that develop Alzheimer's disease. Instead of beta-amyloid plaques, people with diabetes showed arteriol and nerve tissue swelling.
Other negative brain changes are the result of addiction, causing changes in the brain chemistry. Post -traumatic stress disorder (PTSD) and depression also create changes in brain chemistry. The ability to influence brain chemistry is also used to have a good effect in medicines that all three of these disorders treat.
Because the brain structure correlates with the function of the brain, the injury of specific parts of the head can lead to very specific brain changes that result in a very specific deficiency of the function of the brain function. For example, damage to the left temporary lobe may result in affasses - the pronunciation of the ability to express or understand the spoken and/or written language - while damage to the left parietal lobe can result in apraxia - the conviction of the ability to sequence movements into the task.
