Dementia - Causes, Prevention & Treatments

A generic term for cognitive decline that is profound enough to impede daily existence, dementia refers to memory, language, problem-solving, and other cognitive ability loss. The most frequent cause of dementia is Alzheimer’s disease.

When thinking, memory, and reasoning skills are lost to the point where they interfere with day-to-day tasks, this condition is known as dementia. Some dementia patients have emotional instability and personality changes. The intensity of dementia varies from the mildest stage, when it is just starting to interfere with a person’s ability to function, to the most severe level, when the individual must fully rely on others for fundamental daily activities.

As people age, dementia becomes more prevalent (approximately one-third of all adults over the age of 85 may have some kind of dementia), yet it is not a typical aspect of aging. Many people reach their 90s and beyond without displaying any dementia symptoms.

Alzheimer’s disease is one of several different types of dementia. The type of a person’s symptoms can change.

  • Temporary memory
  • Tracking down a phone or bag

Since many diseases grow over time, dementia’s early symptoms gradually worsen as time goes on. Don’t dismiss memory issues or other changes in thinking abilities if you or someone you know is going through them. Visit a doctor right away to ascertain the cause. The right treatment of dementia can be found after professional evaluation. A person can benefit the most from therapies that are currently available and have the option to participate in clinical trials or research if they receive an early diagnosis of dementia, even if symptoms point to the condition. It also gives you time to make plans.

What are the Different Types of Dementia?

  • Dementia that combines two or more different forms is called mixed dementia. For instance, experts have discovered that many persons had a mixture of brain abnormalities linked to various kinds of dementia through postmortem investigations examining adults who had dementia.
  • The underlying condition mechanisms that lead to various forms of dementia are being studied by scientists to learn how they develop and interact. Additionally, they keep researching the various diseases and conditions that cause dementia.
