  • Magnetic Resonance Imaging (MRI)

  • A brain scanning technique that generates cross-sectional images of a human brain by detecting small molecular changes. MRI scans reveal a contrast between normal and abnormal tissues. The image produced is similar to those generated by CT scans. There are no side effects or risks associated with MRI scans, although MRI can affect electrical devices like pacemakers and hearing AIDS.

  • Medicaid

  • A program sponsored by the federal government and administered by states that is intended to provide health care and health-related services to low-income individuals.

  • Medicare

  • A federal health insurance program for people age 65 and older and for individuals with disabilities.

  • Memory

  • The ability to process information that requires attention, storage, and retrieval.

  • Metabolism

  • The complex chemical and physical processes of living organisms that promote growth, sustain life, and enable all other bodily functions to take place.

  • Microglia (MICROGLIAL CELLS)

  • A type of immune cell found in the brain. Microglia are scavengers, engulfing dead cells and other debris. In Alzheimer�s disease, microglia are found associated with dying nerve cells and amyloid plaques.

  • Mid

  • See multi-infarct dementia.

  • Mini-Mental State Examination (MMSE)

  • A standard mental status exam routinely used to measure a person�s basic cognitive skills, such as short-term memory, long-term memory, orientation, writing, and language.

  • Mitochondria

  • Components found in cells that serve as primary energy sources for all cellular functions.

  • Model System

  • A system used to study processes that take place in humans or other living organisms.

  • Monoamine Oxidase B (MAO-B)

  • An enzyme that breaks down certain neurotransmitters, including dopamine, serotonin, and noradrenaline.

  • Monoamine Oxidase Inhibitor (MAOI)

  • A drug that interferes with the action of monoamine oxidase, slowing the breakdown of certain neurotransmitters. Used in the treatment of depression.

  • Mri

  • See magnetic resonance imaging.

  • Multi-Infarct Dementia (MID)

  • A form of dementia, also known as vascular dementia, caused by a number of strokes in the brain. These strokes can affect some intellectual abilities, impair motor and walking skills, and cause an individual to experience hallucinations, delusions, or depression. The onset of MID is usually abrupt and often progresses in a stepwise fashion. Individuals with MID are likely to have risk factors for strokes, such as high blood pressure, heart disease, or diabetes. MID cannot be treated; once the nerve cells die, they cannot be replaced. However, risk factors can be treated, which may help prevent further damage.

  • Music Therapy

  • Use of music to improve physical, psychological, cognitive, and social functioning.
