The limbic system is located under the cerebral cortex. Cerebral cortex part of the cerebrum damage results in trouble controlling emotional outbursts. Brain stem damage late in AD impairs organ function, including the function of the heart, lungs, and various other bodily processes.
For more information regarding structural changes to the brain of an individual with dementia, click here. They have spaces between them called synapses.
Brain chemicals, called neurotransmitters, are released by neurons and deposited into the synapses. Neurotransmitters are important for communication between neurons. This communication is responsible for producing movement and is a critical part of learning and remembering.
When cellular damage due to AD occurs, neurons cannot communicate, and learning and memory are impaired. The neurons eventually die.
Because of all of this damage, the brain gradually shrinks and becomes less functional, leading to many of the symptoms of dementia. Unfortunately, there is no cure for AD, but there are multiple treatments that can slow down the progression of the disease.
However, individuals can live up to 20 years after being diagnosed with the disease. Click on the following links to learn more about Diagnosing Dementia and Treating Dementia.
In the late stage of AD, the damage to the brain is so extensive the inflicted individual often no longer has mobility, causing the individual to be bed bound. These circumstances can lead to sepsis, blood clots, and infections, which may ultimately cause their death.
An individual with late stage AD also has difficulty swallowing, which affects the ability to eat.Alzheimer’s disease is an incurable neurodegenerative disease (progressive loss of neurons) of the brain tissue that causes progressive and irreversible loss of mental functions, including memory.
This is the most common form of dementia in humans.
