This article covers the definition of dementia, as well as its symptoms and causes.

Symptoms increase and usually get progressively worse as someone moves from the early stage to the late stage.

Early Stage Dementia

It’s common to overlook the symptoms of early-stage dementia.

However, a person with early-stage dementia is generally still able to function independently.

Middle Stage Dementia

Symptoms often become more apparent when dementia progresses into this stage.

A person may forget recent events or the names of people close to them.

They may become easily confused, have troublecommunicating, and repeatedly ask questions.

At this stage, a person may need help completing daily tasks, such as those involving personal hygiene.

They may experience changes in personality as well, perhaps becoming agitated more easily.

They may also havedifficulty sleeping.

Late Stage Dementia

Symptoms become the most severe during late-stage dementia.

People with late-stage dementia often require a full-time caretaker.

A doctor will ask about the severity and duration of symptoms.

Unfortunately, there is no single test to diagnose dementia.

There are also genetic tests available to measure someone’s risk of developing dementia.

It can take months for healthcare professionals to make an official diagnosis of dementia.

For this reason, it’s helpful if family members and loved ones continue to document signs and symptoms.

Causes of Dementia

Dementia is the result of damage to the brain cells.

Researchers are still learning what actually contributes to the damage to these cells.

Risk factors include:

Types of Dementia

There are many different types of dementia.

Reminiscence therapymay also help promote psychological well-being in people with dementia.

During reminiscence therapy, a therapist encourages a client to recall memories of their own life.

A reminiscence therapist may use videos, recordings, photos, and more to help a person remember.

Music therapyandart therapymayimprove the quality of lifeof someone with dementia.

Engaging in enjoyable activities, in general, can help to boost mood and be a useful outlet.

It’s worth noting, however, that most of these medications were specifically designed for Alzheimer’s disease.

Those with pre-existing health conditions such as respiratory disease or seizure disorders should use caution when taking these medications.

ARIA involves temporary swelling of the brain.

A caregiver should monitor a person’s physical and mental health when they take medication for dementia.

Antidepressants and Antipsychotics

Of dementia patients, 63% experience depression.

However, there are resources that can help.

It’s also important that you and/or their caregiver monitor their condition to keep them safe.

Diet and exercise can help support the physical and mental health of someone with dementia.

However, people with middle- to late-stage dementia should be monitored when engaging in physical activity.

Anything strenuous or unsafe should be avoided.

Be on the lookout for signs ofcaregiver burnout.

It’s OK if you choose not to be your loved one’s caregiver.

Talk to a doctor or social worker about potential caregiving alternatives.

Remember, you’re not alone.

A caregiver can help you develop systems and lifestyle changes that can make your daily life easier.

If you are a caregiver, there are resources that can help you cope as well to prevent burnout.

While there is no cure for dementia, there are treatment options that can greatly improve quality of life.
