Alzheimers Disease

It is a chronic neurodegenerative disease that usually starts slowly and gets worse over time.[1][2] The most common early symptom is difficulty in remembering recent events (short term memory loss).[1] As the disease advances, symptoms can include: problems with language, disorientation (including easily getting lost), mood swings, loss of motivation, not managing self care, and behavioural issues.[2][1] As a person's condition declines, she or he often withdraws from family and society.[1] Gradually, bodily functions are lost, ultimately leading to death.[3] Although the speed of progression can vary, the average life expectancy following diagnosis is three to nine years

Stroke

poor blood flow to the brain results in cell death. There are two main types: ischemic due to lack of blood flow and hemorrhagic due to bleeding. They result in part of the brain not functioning properly.[1] Symptoms may include an inability to move or feel on one side of the body, problems understanding or speaking, feeling like the world is spinning, or loss of one vision to one side among others.[2][3] Symptoms usually but not always come on quickly. If symptoms last less than one or two hours it is known as a transient ischemic attack(TIA).[3] Hemorrhage strokes may also be associated with a severe headache.[3] The symptoms of a stroke can be permanent.[1] Long term complications may include pneumonia or loss of bladder control.[3]
