1.1 Describe a range of causes of dementia syndrome
Dementia is a term describing a wide range of symptoms associated with the decline of the memory, or other cognitive or sensorial skills that reduce a person’s ability to perform day by day activities. This term refers to Alzheimer disease, Vascular dementia, Dementia with Lewy bodies, Parkinson’s disease, Creutzfeldt-Jakobs disease, Huntington’s disease in the same time.
What causes this range of diseases varies from bad connections between synapses, bad vascularisation of the brain, abnormal aggregations of proteins in the cortex, degeneration of the nerve cell that produces dopamine, bad distribution of the proteins in the brain, build-up of fluids in the brain or a mixture between them.
1.2 Describe the types of memory impairment commonly by individuals with dementia.
Alzheimer’s disease is the most common type of dementia and is accounted for 60-0% of the cases. The symptoms are: difficulty remembering recent events or names, apathy, depression, communication impairment, poor judgment, disorientation, confusion, behaviour changes, difficulty speaking and swallowing.
Vascular dementia is common to 10% of the cases and involves symptoms like: ability to make decisions, plans or organise, confusion, disorientation, speech or understanding impairment, vision loss.
Dementia with Lewy bodies is manifested by memory loss and thinking problems same like the people with Alzheimer but in the early stages they have sleep disturbances, visual hallucinations and muscle rigidity.
Parkinson’s disease is having as symptoms problems with movement, memory loss, difficulty to speak or to swallow.
Creutzfeld-Jakobs has rapidly fatal disorder that impairs memory and coordination and causes behaviour changes.
Huntington’s disease include abnormal involuntary movements, severe decline in thinking and reasoning, mood changes.
