AD Overview Is the most common form of dementia. There is no cure for the disease, which worsens as it progresses, and eventually leads to death.
AD Overview AD is diagnosed in people over 65 years of age, although early-onset Alzheimer's can occur much earlier.
AD Overview In the early stages, the most common symptom is difficulty in remembering recent events.
AD Overview As the disease advances, symptoms include confusion, aggression, mood swings, trouble with language, and long-term memory loss
AD Overview Gradually, bodily functions are lost, ultimately leading to death.
AD Overview The cause and progression of Alzheimer's disease are not well understood.
AD Overview Research indicates that the disease is associated with plaques and tangles in the brain
AD Overview There are no available treatments that stop or reverse the progression of the disease
AD Overview Mental stimulation, exercise, and a balanced diet have been suggested as ways to delay cognitive symptoms
Early Characteristics The most noticeable deficit is memory loss, which shows up as difficulty in remembering recently learned facts and inability to acquire new information
Early Characteristics Depressive symptoms, irritability and reduced awareness of subtle memory difficulties also occur commonly
Early Characteristics Language problems are mainly characterized by a shrinking vocabulary and decreased word fluency
Advanced Characteristics Language is reduced to simple phrases or even single words, leading to complete loss of speech
Advanced Characteristics People can often understand and return emotional signals
Advanced Characteristics People with AD will ultimately not be able to perform even the simplest tasks without assistance
Advanced Characteristics Muscle mass and mobility deteriorate to the point where they are bedridden, and they lose the ability to feed themselves
Cause of AD The cause for most Alzheimer's cases is still essentially unknown. However, some hypothesis exists.
Cause of AD Beta Amyloid Hypothesis: Protein (beta-amyloid) accumulation in the brain is the fundamental cause of the disease
Cause of AD Support: the location of the gene for the amyloid protein on chromosome 21
Cause of AD Support: people with trisomy 21 (DS) almost universally exhibit AD by 40 years of age
Pathophysiology of AD Alzheimer's disease has been identified as a protein misfolding disease
Pathophysiology of AD Caused by accumulation of abnormally folded beta amyloid proteins in the brain
Pathophysiology of AD Protein accumulation is involved with damage in the brain
Pathophysiology of AD Alzheimer's disease is characterized by damages including the loss of neurons and synapses in the brain

Football & Brain Damage Normally, a protein called S100B is found only in the brain
Football & Brain Damage S100B can found in the blood stream of people that suffered brain injuries
Football & Brain Damage S100B in the blood stream is seen by the immune system as a foreign invader
Football & Brain Damage The immune system attacks the S100B protein in the blood stream as well as in the brain
Football & Brain Damage Leads to immune system attacking brain tissue and causing brain damage
