Alzheimer’s Disease Scenario In World & Bangladesh
According to WHO, In every 3 seconds someone in the world gets dementia. In 2020, there were more than 55 million people worldwide suffering from dementia.
Alzheimer’s disease scenario worldwide According to the WHO data, published in 2020 Alzheimer’s & Dementia Deaths in Bangladesh reached 14,993 or 2.09% of total deaths, that ranks Bangladesh number 142 in the world.
60% of people with dementia live in low- and middle-income countries, but this will increase to 71% by 2050. One in every 12 Bangladeshis over the age of 60 has dementia.
Mission
To aware rural and suburban people about Alzheimer’s disease and its screening method.
To reduce the mortality and morbidity rate for Alzheimer’s disease by early detection.
To ensure Alzheimer’s disease screening accessible and affordable to the people.
Vision
The socio-economic structure in Bangladesh barely gives us an opportunity to build awareness of neurodegenerative disorders like Alzheimer's diseases, which is mostly unknown among the population in Bangladesh. Most of the cases ended up with AD patients not being treated properly and kept beyond the reach of professional resources and facilities. However, there is no effective definite structure in front of us to show how AD affects our society and how we can increase awareness among general people regarding symptoms of AD. This tool will help to evaluate the situation and will help health workers to diagnose AD more promptly and would increase awareness through information technology. Furthermore, this screening tool will help in early identification of AD for an individual and refer them to the available facilities when necessary.
Most Common Warning Signs of Alzheimer’s Disease
Memory loss that disrupts daily life
Challenges in planning or solving problems
Difficulty in completing familiar tasks
Poor judgment and repeating questions
Confusion with time or place
Trouble in understanding visual images and spatial relationships
New problems with words in speaking or writing
Misplacing things and losing the ability to retrace steps
Mood or personality change
Anxiety
About
The Cog-I system is a smart application for Alzheimer’s disease (AD) screening, monitoring, and increasing awareness. The main users of this system are i)people of developing countries having no or limited medical services and professionals available for AD and ii) physicians and AD caregivers living in different locations who can help the patients with screening as well as maintenance using an automated system. The general users will access the system via smartphone App after registering for the first time with assigned unique User ID and password. The system will assess the person’s condition via a screening tool which is developed and validated for early detection of AD considering the user criteria and context of Bangladesh. This screening tool is able to identify the cases who are at the risk of developing AD. The responses will be stored in a cloud database. The system will show a list of AD caregivers and healthcare centers or, doctors with their location maps so that the patient can find out the nearest place to get help.

FAQ
What is the difference between AD & dementia?
Alzheimer's disease is a type of dementia. Dementia is a loss of thinking, remembering, and reasoning
skills that interferes with a person's daily life and activities. Alzheimer's disease is the most common
cause of dementia among older people.
What are the early signs of AD?
The earliest symptoms of Alzheimer's disease might vary from person to person, although memory issues
are often one of the symptoms. The very early stages of Alzheimer's disease may also be indicated by a
deterioration in other cognitive abilities, including the ability to express oneself clearly, problems
with vision or spatial awareness, and impaired reasoning or judgment.
What are the stages of AD?
Mild Alzheimer’s disease
Memory loss and other cognitive problems get worse as Alzheimer's gets worse. Wandering and getting lost can be a problem, as can having difficulties in managing money and paying bills, asking questions repeatedly, taking longer to do everyday duties, and changing their personality and conduct. In this period, patients are frequently diagnosed.
Moderate Alzheimer’s disease
This stage of the disease involves brain damage to the regions responsible for language, cognition, conscious thought, and sensory processing, including the capacity to recognize sounds and scents. As disorientation and memory loss worsen, it gets harder for people to identify their loved ones. They might not be able to adapt to new circumstances, learn new things, or perform complex chores like getting dressed. In addition, individuals in this stage may exhibit impulsive behavior and have hallucinations, delusions, and paranoia.
Severe Alzheimer’s disease
Plaques and tangles eventually cover the entire brain, and the brain's tissue begins to dramatically diminish. People who have advanced Alzheimer's disease are fully reliant on others for their care and are unable to communicate. As the body slows down at the end of life, the person may spend most of the time in bed.

What are the causes of AD?
Researchers still don't fully comprehend why most people develop Alzheimer's disease. Age-related
changes in the brain as well as genetic, environmental, and lifestyle variables are likely contributing
factors. Depending on the individual, each of these characteristics may have a different impact on the
likelihood of developing Alzheimer's disease.
Is AD Hereditary?
A lot of people are concerned about getting Alzheimer's disease, particularly if a family member has
already had it. It's not like that you'll get the illness just because someone in your family had.
However, it can imply that you are more prone to get it. Alzheimer's disease risk can be influenced by
an individual's genes, which they receive from their biological parents. Some diseases run in families
due to these risk factors.
Is there any cure to prevent AD?
At present, there is no cure for Alzheimer's disease. Some sources claim that products such as
coconut oil or dietary supplements can cure or delay Alzheimer's. However, there is no scientific
evidence to support these claims.
What are the factors that contribute to Alzheimer’s disease?
Diet, improper sleep, isolation, sedentary lifestyle, drinking alcohol, head trauma, diabetes,
hypertension in midlife contribute to Alzheimer’s disease.
Do Alzheimer patients sleep a lot?
A person with dementia frequently spends a lot of time sleeping, both during the day and at night,
especially in the latter stages. For the person's relatives and friends, this can occasionally be
upsetting because they may be concerned that something is wrong.
Is Alzheimer’s a mental illness?
No it is not a mental illness. It is a disease of the brain.
