How does cognitive health affect me?
Cognitive health poses as one of the greatest global challenges for health and social care in the 21st century.
In Hong Kong, according to the mental morbidity survey for older people released by The Chinese University of Hong Kong's Faculty of Medicine in 2023, one-fifth of the older adults residing in the community have mild neurocognitive disorder, with 7.4% classified as having dementia.
Globally, dementia affected 50 million people worldwide in 2015 (or roughly 5% of the world’s elderly population, i.e. those above the age of 60 years). The number of people with dementia is expected to increase to 82 million in 2030 and 152 million by 2050 with the estimated proportion of the population aged 60 and over with dementia at a given time between 5 to 8% because dementia rises exponentially during old age, and the world’s population is ageing.
What is Mild Cognitive Impairment (MCI)?
Mild cognitive impairment (MCI) is a condition in which people have more memory or thinking problems than other people their age. People with MCI are at a greater risk of developing dementia.
Individuals with MCI may be aware that their memory or cognitive functions have 'declined.' Family members and close friends may also notice these changes. However, these changes are not significant enough to affect daily life or routine activities.
Early detection and diagnosis are very important for both the person and their families, as there are ways to slow down the rate of degeneration. Hence, reducing caregiver stress and improving the person's quality of life.
What is Dementia?
Dementia is a syndrome caused by brain degeneration or brain disease. The person may experience impairments in memory, comprehension, language, learning, calculation, and judgment, and some may also undergo changes in emotional, behavioral, and sensory functions.
These cognitive health issues not only affect the quality of life for patients but can also place stress on their families and society. Therefore, early identification and intervention are crucial.
