what parts of the brain are affected by vascular dementia?
443621
A different kind of vascular dementia, called subcortical vascular dementia, follows disease of the small blood vessels deep in the brain. This disease often causes widespread damage to white matter beneath the cortex. These nerve fibres carry signals between different parts of the cortex, including the frontal lobes.

The most common types of dementia – Alzheimer's disease, vascular dementia, dementia with Lewy bodies and frontotemporal dementia – are all progressive. This means that the structure and chemistry of the brain become increasingly damaged over time.

Temporal lobe. When a stroke affects the temporal lobe, situated at ear level and underneath both the parietal and frontal lobes, it can produce language problems known as aphasia (difficulty understanding speech, verbalizing thoughts, reading, or writing).

Summary: Scientists have uncovered a potential approach to treat one of the commonest causes of dementia and stroke in older people. Studies with rats found the treatment can reverse changes in blood vessels in the brain associated with the condition, called cerebral small vessel disease.

Symptoms specific to vascular dementia Symptoms can sometimes develop suddenly and quickly get worse, but they can also develop gradually over many months or years.

If blood flow is only interrupted for short time, it's known as a transient ischemic attack (TIA), or “ministroke.” TIA symptoms lasts less than 24 hours before disappearing. Both ischemic stroke and TIA are associated with vascular dementia. Vascular dementia is the second most common form of dementia.

There are over 400 different types of dementia, the most common of which are Alzheimer's disease and vascular dementia. There are over 400 different types of dementia. The most common types are Alzheimer's disease and vascular dementia.

High blood pressure contributes to cerebral small and large vessel disease resulting in brain damage and dementia. A decline in cerebrovascular reserve capacity and emerging degenerative vascular wall changes underlie complete and incomplete brain infarcts, haemorrhages and white matter hyperintensities.

Strokes, depression, excessive long-term alcohol consumption, infections, hormonal disorders, nutritional deficiencies and brain tumours can all cause dementia-like symptoms. Many of these conditions can be treated.

Vascular cognitive impairment is a disorder of the mind – the mental ability to be aware, to think and to feel. VCI symptoms can range from forgetfulness to more serious problems with attention, memory, language, and executive functions like problem solving. The most serious form of VCI is called vascular dementia.

Vascular dementia can be slowed down in some cases, but it still shortens a person's lifespan. Some types of dementia are reversible, but most types are irreversible and will instead cause more impairment over time. Alzheimer's is a terminal illness, and no cure is currently available.

As vascular dementia progresses, the symptoms become closer to those of middle and eventually later stage Alzheimer's disease. Problems with memory loss, confusion, disorientation, reasoning and communication all become worse.

Aphasia symptoms associated with dementia People with the most common types of dementia, such as Alzheimer's disease and vascular dementia, usually have a mild form of aphasia. This often involves problems finding words and can affect names, even of people they know well.

Dementia is an umbrella term used to describe a range of progressive neurological disorders, that is, conditions affecting the brain. There are over 200 subtypes of dementia, but the five most common are: Alzheimer's disease, vascular dementia, dementia with Lewy bodies, frontotemporal dementia and mixed dementia.
