Transcript of Alzeihmer's Disease
• In the Cerebral Cortex of the Brain, it shrinks and the areas of thinking , planning and remembered are damaged
• The Hippocampus (an area of the cortex), is shrunk and severely damaged. when does it occur? AS WE AGE After the age of 65 the risk of having this disease is 1 in 100. Between the age of 75-84 the risk of having this disease is 1 in 14. After the age of 85 the risk of having this disease is 1 in 4 Who can have it? • Family History of Alzheimer’s
• Down syndrome
• Past Head Injuries
• Heart Disease Risk Factors
Why it happens is yet to be determined by neurologists Why does it happen As the disease progresses, nerve cells end up dying and neurotransmitter also begin to decline; acetylcholine is deficient in those who have Alzheimer’s disease. Alzheimer’s disturbs the way the impulse of electricity runs through the neurons within the brain cells not allowing cells to communicate between one another, causing the nerve cells to die and the brain to shrink. BUT How Does It Happen? Medical Terminology
De/ment/ia – (“De” prefix = without, “ment” root of mens =minds, “ia” = condition) “condition of loss of mind” The loss of mental/brain functions, that interferes in a person’s daily living.
Neur/ons – (“neur”= nerve “ons“ = cell ) “nerve cell” A nerve cell that is made of: a cell body containing a nucleus, dendrites, and an axon. This cell in the nervous system sends signals to other cells throughout the body that directs actions of the body.
Cerebr/al Cortex ( “cerebr” – cerebrum “al”– pertaining to “cortic/o” cortex = outer region) “pertaining to the outer region of the cerebrum”– It is an outer layer of the brain where the thought process occurs. This is where the nerves cells in the cortex die when Alzheimer’s
Neuro/logy- (“Neuro”= Nerves “logy” = study of ) “study of nerves” - it is the study of the nervous system which includes any part of the brain
Neur/o/logist – (“neuro”= brain,nervous system, nerves “gist” = specialist ) “Specialist in study of the nervous system” - A medical specialist who studies the nervous system and diseases involving it.
