Types of cognitive decline

- Mild cognitive decline (MCI): people with MCI may notice difficulties with memory or attention, but generally can still perform their daily activities independently. This type of decline can be identified by cognitive testing.
- Severe cognitive decline (often associated with dementia): this type of decline involves significant loss of cognitive abilities, such as comprehension, language, and writing. People with dementia are often unable to live independently.


Risk factors and prevention

Cognitive decline can affect people of all ages, but it is more common in the elderly.
Risk factors include:
- Advanced age
- Genetics
- Pre-existing health conditions: Diabetes, hypertension, cardiovascular disease
- Poor lifestyles: Smoking, alcohol abuse, lack of physical activity, unbalanced diet
Fortunately, several strategies can slow or even prevent cognitive decline:
- Mental activity: reading, playing puzzle games, learning new languages or doing creative activities.
- Physical activity: practice regular exercise to improve blood circulation and brain health.
- Healthy eating: prefer a diet rich in fruits, vegetables, whole grains and healthy fats.
- Stress management: reduce stress through techniques such as yoga or meditation
- Socialization: maintain active and frequent social relationships.


Diagnosis and measurement

The diagnosis of cognitive decline is made through a comprehensive medical evaluation. Various tests exist to measure cognitive decline, among the most widely used is the Mini-Mental State Examination (MMSE): This test assesses cognitive functions such as memory, attention, and ability to answer questions


In conclusion, cognitive decline, which can range from mild to severe, is a condition that requires attention and early intervention. Recognizing its symptoms, understanding risk factors, adopting preventive strategies, and measuring cognitive function through specific tests are key steps to manage and mitigate the effects of cognitive decline. In addition, treating associated conditions can help maintain and improve the quality of life of people with cognitive decline.
