What is dementia

Dementia describes a collection of symptoms that are caused by disorders affecting the brain. It is not one specific disease.

Dementia affects thinking, behaviour and the ability to perform everyday tasks. Brain function is affected enough to interfere with the person’s normal social or working life.

What causes dementia?

Dementia is caused by damage to brain cells. This damage interferes with the ability of brain cells to communicate with each other. When brain cells cannot communicate normally, thinking, behavior and feelings can be affected. The brain has many distinct regions, each of which is responsible for different functions (for example, memory, judgment and movement). When cells in a particular region are damaged, that region cannot carry out its functions normally.

Symptoms of dementia

If you or your loved one is experiencing memory problems, don’t immediately conclude that it’s dementia. A person needs to have at least two types of impairment that significantly interfere with everyday life to receive a dementia diagnosis.

In addition to difficulty remembering, the person may also experience impairments in:

  • Language

  • Communication

  • Focus

  • Reasoning

Subtle short-term memory changes

Trouble with memory can be an early symptom of dementia. The changes are often subtle and tend to involve short-term memory. An older person may be able to remember events that took place years ago but can’t remember what they had for breakfast. Other symptoms of changes in short-term memory include forgetting where they left an item, struggling to remember why they entered a particular room, or forgetting what they were supposed to do on any given day.

Difficulty finding the right words

Another early symptom of dementia is struggling to communicate thoughts. A person with dementia may have difficulty explaining something or finding the right words to express themselves. Having a conversation with a person who has dementia can be difficult, and it may take longer than usual to conclude.

Dementia treatment and care

Treatment of dementia depends on its cause. In the case of most progressive dementias, including Alzheimer’s disease, there is no cure and no treatment that slows or stops its progression. But there are drug treatments that may temporarily improve symptoms. The same medications used to treat Alzheimer’s are among the drugs sometimes prescribed to help with symptoms of other types of dementias. Non-drug therapies can also alleviate some symptoms of dementia.

Ultimately, the path to effective new treatments for dementia is through increased research funding and increased participation in clinical studies. Right now, volunteers are urgently needed to participate in more than 180+ actively enrolling clinical studies and trials about Alzheimer’s and related dementias.
