September is World Alzheimer’s Month

Every September 21st is World Alzheimer’s Day, and the whole month of September is proclaimed World Alzheimer’s Disease Month by an international campaign by Alzheimer’s Disease International to raise awareness and break the stigma around this topic of this difficult disease.

What is Alzheimer’s disease?

This chronic disease is the process of abrupt reduction of dementia symptoms affecting the brain, where memory and thinking are lost, as well as the ability to perform other daily tasks.

The National Health Service of the UK National Health Service writes,

Alzheimer’s disease is thought to be caused by the abnormal buildup of proteins in and around brain cells. Although it’s unclear exactly what triggers this process, scientists now know that it begins several years before symptoms appear.

As brain cells are affected, there is also a decrease in chemical messengers (called neurotransmitters) involved in sending messages or signals between brain cells. Levels of a neurotransmitter, acetylcholine, are particularly low in the brains of people with Alzheimer’s disease.

Over time, different areas of the brain shrink. The first areas usually affected are responsible for memories. In the more unusual forms of Alzheimer’s disease, different areas of the brain are affected.

Of the brain

The Mayo Clinic writes that while the exact reasons aren’t yet known, the proteins involved in the process are recognized and being researched.

The exact causes of Alzheimer’s disease are not fully understood, but at its root are problems with brain proteins that don’t function normally, disrupt the work of brain cells (neurons) and trigger a series of toxic events. Neurons are damaged, lose their connections and eventually die.

The damage most often begins in the region of the brain that controls memory, but the process begins years before the first symptoms appear. The loss of neurons spreads in a somewhat predictable pattern to other regions of the brain. In the advanced stage of the disease, the brain has shrunk considerably.

Researchers are focusing on the role of two proteins:

  • Platelets. Beta-amyloid is a residual fragment of a larger protein. When these fragments come together, they seem to have a toxic effect on neurons and disrupt intercellular communication. These clumps form larger deposits called amyloid plaques, which also include other cellular debris.
  • Tangles. Tau proteins play a role in the internal support and transport system of a neuron to transport nutrients and other essential materials. In Alzheimer’s disease, tau proteins change shape and organize into structures called neurofibrillary tangles. Tangles disrupt the transport system and are toxic to cells.

In simpler terms, the most important issues central to the development of Alzheimer’s disease relate to brain proteins. Their inability to perform their tasks causes neurons to become distraught, which are then damaged.

This is significantly detrimental, as neurons are the fundamental units of the brain; in simple terms, their purpose is to receive information and direct signals to other neurons in the fast system. They may very well be considered messengers, but when these deliveries fail, the whole body begins to deteriorate.

Possible reasons and factors

There is no clear reason why this disease occurs, but one of the most well-known causes is age. According to the Alzheimer’s Association, the vast majority of people with Alzheimer’s disease are over the age of 65. However, many are also diagnosed at age 65, also known as early-onset Alzheimer’s disease.

Besides abnormal protein accumulation and age, the NHS lists genetics as a possible contributing factor to this disease, although the actual increase in risk is not that high.

The NHS has also published that people with Down’s syndrome are also at higher risk of getting Alzheimer’s disease because “the genetic defect that causes Down’s syndrome can also cause amyloid plaques to build up in the brain. over time, which can lead to Alzheimer’s disease in some people.”

Research also shows, the NHS notes, that cardiovascular disease can be seen as a factor in increasing the risk of this disease. The NHS writes that people with smoking, obesity, diabetes, high blood pressure and high cholesterol may be at high risk.

Last but not least, surprisingly, many scientists suspect that severe head trauma may be linked to Alzheimer’s disease risks, although research into this speculation is sparse and requires more focus.


According to the National Institute on Aging of the United States Department of Health and Human Services, the first signs of Alzheimer’s disease can be very varied and depend on each person and each case.

Early symptoms of Alzheimer’s disease vary from person to person. Memory problems are usually one of the first signs of cognitive impairment in Alzheimer’s disease. Decline in non-memory aspects of cognition, such as word finding, vision/spatial problems, and impaired reasoning or judgment, may also signal the very early stages of Alzheimer’s disease. And some people can be diagnosed with mild cognitive impairment.

As the disease progresses, people experience greater memory loss and other cognitive difficulties. Alzheimer’s disease progresses through several stages: preclinical, mild (sometimes called early stage), moderate and severe (sometimes called advanced stage).

What will change?

The Mayo Clinic considers memory loss its biggest change, along with the inability to remember recent events and to speak. They list that:

People with Alzheimer’s can:

  • Repeat statements and questions over and over
  • Forget conversations, appointments or events, and don’t remember them later
  • Regularly misplacing possessions, often placing them in illogical places
  • Get lost in familiar places
  • Eventually forget the names of family members and everyday objects
  • Having trouble finding the right words to identify objects, express thoughts or take part in conversations

Multitasking will become a challenge for people with Alzheimer’s disease, as will the ability to make decisions and choices.

The brain changes that occur during this form of dementia can also affect someone’s personality. The Mayo Clinic lists what one might possibly experience:

Depression, apathy, social withdrawal, mood swings, distrust of others, irritability and aggression, changes in sleep patterns, wandering, loss of inhibitions, delusions, such as believing something has been stolen

Preservation of certain skills

However, according to the Mayo Clinic, not all will be lost quickly. Some preserved skills may last longer, as these areas are stored in affected parts of the brain much later than others. This can include skills such as art, reading, singing, etc.

Can this be avoided?

Unfortunately, there is no clear vaccine or treatment to cure this disorder, but the Mayo Clinic has published some methods that can be tried to modify the degree of risk. Efforts to maintain a healthy diet, regular exercise, good management of high blood pressure, diabetes, and high cholesterol, and a tobacco-free routine are recommended steps to significantly reduce risk.
