Cognitive decline is linked to a range of factors, including aging, genetics, lifestyle, and medical conditions. It can affect memory, language, problem-solving, and other thinking skills.
Aging
As we age, our cognitive abilities naturally decline. The most common age-related cognitive decline is mild cognitive impairment (MCI). MCI is a condition in which an individual has noticeable memory loss and other cognitive deficits, but still has the ability to function independently.
Genetics
Genetics play a role in cognitive decline as well. Certain genetic conditions, such as Alzheimer’s disease and frontotemporal dementia, are associated with cognitive decline. In some cases, the genes associated with these conditions may be inherited from family members.
Lifestyle
Lifestyle factors, such as physical inactivity, poor diet, smoking, and alcohol use, can also contribute to cognitive decline. Additionally, chronic stress, depression, and sleep deprivation can affect cognitive abilities.
Medical Conditions
Medical conditions, such as stroke, traumatic brain injury, and a number of neurological disorders, can cause cognitive decline. Additionally, certain medical treatments, such as chemotherapy and radiation, can also lead to cognitive impairment.
