1.1 Describe a range of causes of dementia syndrome
1.2 Describe the types of memory impairment commonly experienced by individuals with dementia.
Dementia is an illness which causes the sufferer to lose basic cognitive ability and loss of reality perception.

Their different types of dementia and are classed by the type of harmful proteins the most common of which are:-

Alzheimer’s Disease
This is the most common form of dementia and affects people’s abilities to remember recent events and learn new things. People also experience increased irritability, anxiety, depression, confusion, and restlessness. People who suffer from this form of dementia will also tend to become confused easily, misplace things and often repeat things. Alzheimer’s disease is medically known as atrophy. The area of the brain which is most affected by this from of dementia is the cerebral cortex. The cerebral cortex is a main functioning part of the brain responsible for processing thought and performing many complex functions. The effect of Alzheimer’s is caused by the build-up clumps of protein known as Plagues and Trangles this build up then interferes with the communication pathways of the brain resulting in the symptoms described above.

This form of dementia affects peoples memory functions both short and long term. Suffers can also experience erratic mood swings like suddenly laughing or crying. People with this form of dementia can also experience loss of bowel and bladder control, and at the extreme of this can have symptoms like paralysis difficulty with language and loss of vision.
