Alzheimer’s disease: definition and symptoms
Alzheimer is a progressive disease particularly causing memory, thought and behavioural disorder. More often than not, the signs of the disease appear slowly and evolve over time. Depending on the patients, the disease can develop more or less rapidly, usually over 5 to 20 years.
While the people suffering from the disease are invariably over 65 years of age, it should be noted however that it is not exclusively linked to ageing. The onset of Alzeimer’s can be earlier, often between the ages of 40 and 50 for some 5% of people suffering from the disease.
Unfortunately, no treatment yet exists, but there are solutions which slow down the progression of the disease. That can address the symptoms so as to improve the quality of life of those suffering.
Three categories of symptoms can be mentioned:
- Cognitive symptoms: memory problems, language disorders, difficulty in carrying out complicated activities (managing a budget, preparing a meal, etc.) or recognising family members.
- Emotional and psychological disorders: anxiety, apathy (decrease inmotivation, loss of interest for leisure activities, etc.), irritability, euphoria or even depression.
- Behavioural problems: aggressiveness, aberrant behaviour, sleep and appetite disturbances, disinhibitionor even hallucinations.
To date, a lot of biomedical research has been conducted into the disease. The objective: describe the overall symptoms and find a treatment to combat the illness.
