People with Alzheimer’s disease contain two abnormal structures that damage and kill nerve cells.

  • Amyloid plaques – Deposits of a protein fragment called beta- amyloid builds up in spaces between the nerve cells
  • Tau tangles – Twisted fibers of a protein called tau builds up inside nerve cells

  • Rise of dementia is mostly attributed to people living in low- and middle-income countries
  • Dementia also affects young people and is known as young-onset dementia

History of World Alzheimer’s Day

World Alzheimer’s Day is an initiative of Alzheimer’s Disease International (ADI).

World Alzheimer’s Day was first launched on 21st September 1994 at the opening of ADI’s annual conference in Edinburg to celebrate the 10th Anniversary of ADI.

World Alzheimer Report 2020

Every year ADI launches a World Alzheimer Report on World Alzheimer’s day.

The World Alzheimer Report 2020 is titled ‘Design, Dignity, Dementia-dementia-related design and the built environment’.

The report talks about the best practices, design principles, applications, innovators, regional and cultural contexts and the importance of including dementia people in every stage of the design process.

Alzheimer’s Disease and Dementia during COVID-19

Dementia does not increase the risk of developing COVID-19. However, dementia-related behaviors may increase the risk of COVID-19.

For example, people with Alzheimer’s disease may forget to wash their hands, increasing the risk of contracting COVID-19.

Dementia patients need to stick to their daily routine. However, COVID-19 may disrupt the daily routine and have effects on the behavior of dementia patients.

Disruption of routine may also increase stress and result in loneliness and sadness in dementia patients.

Dementia caregivers need to notice the worsening of dementia symptoms and seek immediate medical attention if needed.

Five Foods that Boost Brain Health

The food a person consumes may play a role in preventing Alzheimer’s disease and dementia. The five foods that can boost brain health are:

  • WalnutsWalnuts can improve memory as they are excellent sources of protein and healthy fats. They are rich in a type of omega-3 fatty acid which can protect arteries and lower blood pressure.
  • Fatty fish – Fatty fishes are abundant in omega-3 fatty acids, unsaturated fats that can lower blood levels of beta-amyloid. Eating salmon, cod, or canned light tuna twice a week can be beneficial.
  • BroccoliBroccoli is a good source of vitamin K. It can enhance cognitive function and improve brainpower. It also contains glucosinolates, which play an essential role in maintaining acetylcholine in the central nervous system. Low levels of acetylcholine are associated with Alzheimer’s disease.
  • AvocadosAvocados are rich in omega fatty acids and vitamin E. Vitamin E may slow the progression of Alzheimer’s disease.
  • Whole grains – Whole grains contain omega 3, complex carbohydrates and vitamin B that support normal brain function.

In summary, it is important to spread awareness about Alzheimer’s disease and dementia on World Alzheimer’s Day. Early diagnosis of Alzheimer’s disease can help the person live a more quality life.
