What are the types of Dementia?
Experts believe that 60% to 80% of people with dementia are diagnosed with Alzheimer’s. It’s what most people think about “dementia.” Memory loss and difficulty doing familiar tasks are the symptoms that can worsen after years. The patient might have a problem knowing the date and where they are, have difficulty writing or speaking, are unable to find their belongings, and become moody. The disease is caused by major, or several small and “silent” strokes, which can happen without the sufferer noticing it. The symptoms vary based on the level of damages strokes give to the brain. We know that Alzheimer’s starts with memory loss, but vascular dementia usually begins with unacceptable judgment or difficulty planning, organizing, and making decisions. Other symptoms can be:
• Becoming moody
• Walking problems and having usual falls
• Trouble understanding speech and speaking
There are four common types of dementia:
1. Alzheimer’s Disease
It is the most common form of dementia, and it results from the brain’s natural ageing processes speeding up. It is not the result of one single factor; heart disease and family history have a significant role. Unfortunately, it’s a degenerative disease, so that the symptoms will worsen over time.
2. Vascular dementia
It is the second – most common type of dementia in older people. Vascular dementia is caused by the shortage of oxygen to brain cells, causing cells damage. As an outcome, brain activity decreases. A considerable slowness of thought characterizes vascular dementia, a progressive condition that worsens over time. The people who suffer from this condition need full-time care.
3. Frontotemporal dementia
After Alzheimer’s and Vascular Dementia, Frontotemporal Dementia (FTD) is the third most common type of dementia in people under 65. Both frontal and temporal lobes of the brain are affected by brain cell injury. Since these are the parts of the brain involved with problem-solving, behaviour, and recognition, patients with frontotemporal dementia often struggle with these tasks.
4. Dementia with Lewy Bodies
Another type of dementia is Lewy Bodies dementia. A build-up of proteins called Lewy Bodies in the body causes this dementia. This illness also develops Parkinson’s disease, with similar symptoms like diminished mobility and stumbling walks.
Dementia is a progressive degenerative disease currently with no cure. It often starts mild and gets worse over time. It is often ignored as simple “old age” in its earliest stages. There are over 100 forms of dementia, but the most common form of dementia is Alzheimer’s disease, impacting between 50–70% of all suffers. Followed by vascular at around 25%, then Lewy Body at approximately 15%, the frontal lobe is the last. It’s possible to have more than one type of dementia. Other medical conditions can also induce dementia symptoms, such as Parkinson’s disease.
Dementia on its own cannot be called a disease but a syndrome that shares its symptoms with certain brain diseases. Particular medications are also advised to limit the progress speed of dementia (behavior changes, for instance). Dementia has different types, and its treatment depends on the type of dementia your loved one suffers:
• Dementia With Lewy Bodies (DLB)
When microscopic deposits of a protein (called Lewy bodies) are formed inside someone’s brain, it can cause a type of dementia called dementia with Lewy Bodies.
• Parkinson’s Disease Dementia
Approximately 50% to 80% of the time, ten years after someone is diagnosed with Parkinson’s disease (a type of nervous system dysfunction), they will eventually get a particular kind of dementia called Parkinson’s disease dementia.
• Alzheimer’s Disease
According to experts, around 60% to 80% of people dealing with dementia have Alzheimer’s disease, too.
• Fronttotemporal Dementia (FTD)
If the brain cells responsible for specific human characteristics (including sentiments, movement, speech, judgment, and planning) are damaged, they’ll likely have frontotemporal dementia.
• Vascular Dementia
When a person experiences a major stroke or one (or several) more minor silent strokes without noticing it, they’re probably dealing with vascular dementia.
• Mixed Dementia
This kind of dementia is a mixture of two other types of dementia, with the most frequent combination being vascular dementia and Alzheimer’s.
