Alzheimer’s disease is the most common cause of dementia

by Dr. Sindhu Vasireddy, Neurologist, Aster Prime Hospital, Ameerpet, Hyderabad.

Every 3 seconds, someone in the world develops dementia. The number of people living with dementia around the world is over 50 million, which is expected to almost double every 20 years, reaching 152 million by 2050.

Alzheimer’s disease is a progressive disorder that causes brain cells to waste away (degenerate) and dies. Alzheimer’s disease is the most common cause of dementia — a continuous decline in thinking, behavioural and social skills that disrupts a person’s ability to function independently.

Dementia knows no social, economic or geographical boundaries. Although each person will experience dementia in their own way, eventually those affected are unable to care for themselves and need help with all aspects of daily life. There is currently no cure for most types of dementia, but treatments, advice, and support are available.

Dementia is now widely recognised as one of the most significant health crises of the 21st century.  This is where WHO has recognised the problem and decided to create awareness on Alzheimer that causes Dementia.

World Alzheimer’s Month 2020

21st September 2020 is World Alzheimer’s Day that is observed as part of Alzheimer’s Month campaign, an international campaign to raise dementia awareness and challenge stigma.  The primary objective of World Alzheimer’s Month is to reach out to as many countries as possible, showing the global impact of dementia and promoting dementia awareness and what we can do to help support those living with the disease.

The Theme – Let’s talk about dementia,

The theme of this year’s campaign mainly stress on speaking out about the disease –

Talking about dementia helps tackle the stigma, normalises language and encourages people to find our more information, advice and seek help.

Then what is Dementia?

Dementia is a collective name for progressive degenerative brain syndromes which affect memory, thinking, behaviour and emotion. Alzheimer’s disease and vascular dementia are the most common types of dementia, responsible for up to 90% of cases of dementia.

Taking care of those suffering with Dementia
For people living with dementia, increased confusion is often the first symptom of any illness. If a person living with dementia shows rapidly increased confusion, contact your health care provider for advice. Unless the person is having difficulty breathing or a very high fever, it is recommended that you call your health care provider instead of going directly to an emergency room. Your doctor may be able to treat the person without a visit to the hospital.
People living with dementia may need extra and/or written reminders and support to remember important hygienic practices from one day to the next.
Consider placing signs in the bathroom and elsewhere to remind people with dementia to wash their hands with soap for 20 seconds.
Demonstrate thorough hand-washing.
Alcohol-based hand sanitizer with at least 60% alcohol can be a quick alternative to hand-washing if the person with dementia cannot get to a sink or wash his/her hands easily.
Ask your pharmacist or doctor about filling prescriptions for a greater number of days to reduce trips to the pharmacy.
Think ahead and make alternative plans for the person with dementia should adult day care, respite, etc. be modified or cancelled in response to COVID-19.
Think ahead and make alternative plans for care management if the primary caregiver should become sick.
Dangers during COVID Pandemic

Alzheimer’s disease does not increase the risk of a COVID-19 infection, but increased age and associated health conditions such as dementia may pose a risk.
Those who show symptoms of dementia may forget to wash their hands or take other recommended precautions to prevent illness. In these cases, family members and caregivers can help by offering additional reminders or written notes and signs.
If they show symptoms of COVID-19, family members and caregivers should avoid visiting patients in nursing homes or other places until their self-isolation period is complete.
In addition, diseases like COVID-19 and the flu may worsen cognitive impairment due to dementia.
