Alzheimer's disease is a neurodegenerative disease that begins slowly and gradually degenerates. It is the explanation for 60%-70% cases of dementia. The most common early symptoms are difficulty in remembering recent events. As the disease progresses, symptoms can include problems with language, disorientation, mood swings, loss of motivation, self- neglect, and behavioural issues. As a person's condition reduces, they often quit from family and society. Gradually, bodily functions are lost, eventually resulting in death.
Dementia exhibits as a group of related symptoms, which usually surface when the brain is impaired by injury or disease. The symptoms involve progressive impairments to memory, thinking, and behaviour, which negatively impact an individual's ability to function and perform everyday activities. Apart from memory impairment and a disorder in thought patterns, the foremost common symptoms include emotional problems, difficulties with language, and decreased motivation.
A mental disturbance, also called a mental disease or psychiatric disorder may be a behavioural or mental pattern that causes remarkable distress or disability of private functioning. Such features could even be persistent, relapsing and remitting, or occur together episode. Many disorders have been expressed, with signs and symptoms that differ broadly between specific disorders.
Parkinson's disease (PD) may be a long-term disorder of the central nervous system that mainly affects the motor system. The symptoms usually surface slowly, and as the disease deteriorates, non-motor symptoms become more common. The most clear early symptoms are tremor, rigidity, slowness of movement, and difficulty with walking. Cognitive and behavioural problems also can occur with depression, anxiety, and apathy occurring in many folks with PD.
A Transient Ischemic Attack (TIA), commonly referred to as a mini- stroke, may be a brief episode of neurological dysfunction caused by loss of blood flow (ischemia) within the brain, medulla spinal cord or retina, without tissue death (infarction).TIAs have an equivalent underlying mechanism as ischemic strokes. Both are caused by an interruption in blood flow to the brain, or Cerebral Blood Flow (CBF). The definition of TIA was classically supported duration of neurological symptoms. The current widely accepted definition is named "tissue-based" because it's supported imaging, not time.
A stroke may be a medical condition during which poor blood flow to the brain causes necrobiosis. There are two main sorts of stroke: ischemic, due to lack of blood flow, and haemorrhagic, thanks to bleeding. Both cause parts of the brain to prevent functioning properly. Signs and symptoms of a stroke may include an inability to feel on one side of the body, problems understanding or speaking, dizziness, or loss of vision to one side. Signs and symptoms often appear soon after the stroke has occurred. If symptoms last but one or two hours, the stroke may be a Transient Ischemic Attack (TIA), also called a mini-stroke. A haemorrhagic stroke can also be related to a severe headache. The symptoms of a stroke are often permanent. Long-term complications may include pneumonia and loss of bladder control.
