The ageing population in Brisbane is becoming more concerned about their memory, thinking, and behaviour. Ubuntu Medical recommends consulting an Alzheimer’s disease specialist for preventive care.

Defining Alzheimer’s Disease

Alzheimer’s Disease is a type of dementia that is progressive and irreversible disorder that slows memory and thought processing skills of individuals. As the illness becomes worse, the individual afflicted would have challenges carrying out even the simplest of tasks. Alzheimer’s disease usually surfaces at the age of 60 and has been identified as one of the leading costs of death among older people.

Alzheimer’s Disease is the most common type of dementia among elders. Dementia is the condition of losing cognitive functioning such as thinking, remembering, and reasoning. Behavioural abilities are also affected to the extent that it interferes with a person’s day-to-day activities.

Signs and Symptoms of Alzheimer’s Disease

Memory problems are the first signs of Alzheimer’s disease. Individuals with Mild Cognitive Impairment (MCI) can be at greater risk of developing Alzheimer’s disease. Having memory problems along with mobility issues and sense of smell are linked to MCI.

The symptoms of Alzheimer’s may vary from person to person. Some may experience a decline in other aspects of cognition such as word-finding, spatial issues, or reasoning and judgement. There have been ongoing researches to detect brain changes of people with MCI and how this contributes to having an Alzheimer’s disease.

Causes of Alzheimer’s Disease

Studies conducted on Alzheimer’s disease state that it is caused by genetics, lifestyle, and environmental factors that affect the brain as time passes.

The causes of Alzheimer’s disease remains to be understood. However, it is clear that the illness causes damage to the brain and kills the brain cells. When the brain cells die, the brain shrinks.

There are two types of abnormalities that are considered origins of the disease:

  • Plaques. These are clumps of beta-amyloid, a type of protein that damages the brain cells and interferes with cell interactions.
  • Tangles. The threads of tau protein become tangled inside the brain cells, hence difficulty in transmitting of stimulus.

Risk Factors of Alzheimer’s Disease

The following has been observed to contribute to having an Alzheimer’s disease.

  • Age. Having an Alzheimer’s disease once an individual reaches the age of 60. Individuals with a family history of Alzheimer’s can experience the symptoms once they hit their 30s.
  • Family history and genetics. The gene apolipoprotein e4 (APoE4) has seen to increase the risk factors of having Alzheimer’s disease.
  • Down Syndrome. The signs and symptoms of Alzheimer’s disease appear 10 to 20 years earlier for individuals with this condition.
  • Gender. Women are more likely to develop Alzheimer’s than men because they tend to live longer.
  • Head Trauma. Severe head trauma increases the risk of having Alzheimer’s disease later in life.
  • Lifestyle health. Similar factors that put you at risk of heart disease can also contribute to having Alzheimer’s disease.

Preventing Alzheimer’s Disease

Studies are still being conducted to prevent Alzheimer’s disease. However, it is definite that in order to lower the risk of Alzheimer’s disease, you should take of your heart health. Having a balanced diet and regular exercise would keep you healthy physically, mentally, and socially.

Having mentally-stimulating and educational activities also lowers the risk of Alzheimer’s disease.
