Dementia with Lewy bodies (DLB) is a type of dementia, a group of diseases involving progressive neurodegeneration of the central nervous system. [ 11 ] It is one of the two Lewy body dementias, along with Parkinson's disease dementia. [ 12 ] Dementia with Lewy bodies can be classified in other ways.
Alzheimer's disease (AD) is a neurodegenerative disease that usually starts slowly and progressively worsens, [ 2 ] and is the cause of 60–70% of cases of dementia. [ 2 ][ 15 ] The most common early symptom is difficulty in remembering recent events. [ 1 ] As the disease advances, symptoms can include problems with language, disorientation ...
A neurodegenerative disease is caused by the progressive loss of neurons, in the process known as neurodegeneration. [2][3] Neuronal damage may also ultimately result in their death. Neurodegenerative diseases include amyotrophic lateral sclerosis, multiple sclerosis, Parkinson's disease, Alzheimer's disease, Huntington's disease, multiple ...
It is located above the brain stem, posterior to the brain. Cerebellar degeneration is a condition in which cerebellar cells, otherwise known as neurons, become damaged and progressively weaken in the cerebellum. [ 1 ] There are two types of cerebellar degeneration; paraneoplastic cerebellar degeneration, and alcoholic or nutritional cerebellar ...
More than one type of dementia, known as mixed dementia, may exist together in about 10% of dementia cases. [2] The most common type of mixed dementia is Alzheimer's disease and vascular dementia. [87] This particular type of mixed dementia's main onsets are a mixture of old age, high blood pressure, and damage to blood vessels in the brain. [15]
Glia, also called glial cells (gliocytes) or neuroglia, are non- neuronal cells in the central nervous system (brain and spinal cord) and the peripheral nervous system that do not produce electrical impulses. The neuroglia make up more than one half the volume of neural tissue in the human body. [ 1 ]
Signs and symptoms. Frontotemporal dementia is an early onset disorder that mostly occurs between the ages of 45 and 65, [ 13 ] but can begin earlier, and in 20–25% of cases onset is later. [ 11 ][ 14 ] Men and women appear to be equally affected. [ 15 ] It is the most common early presenting dementia. [ 16 ]
One study looked at reminiscence therapy for people with two types of dementia: Alzheimer's disease and vascular dementia. [18] Those with Alzheimer's disease experienced significant improvement of withdrawal (so they withdrew less and interacted with others more) compared with the control group immediately after intervention.
