Dementia is a category of degenerative psychiatric disorders characterized by a significant loss of cognitive ability that extends beyond normal aging. Confusion, mood swings, long-term memory loss, and gradual loss of physiology are all symptoms. The most common type of dementia is Alzheimer's disease. This is caused by the accumulation of plaques in neurons in the brain, destroying their function and ultimately killing them. There is no cure for the disease, but new studies suggest that it can be detected early. The first signs of dementia may appear 18 years before diagnosis.
According to a study of more than 2,000 people, memory and thinking tests can reveal differences between people who develop Alzheimer's disease 18 years before diagnosis. Low cognitive test scores were associated with an 85% increased risk of future dementia, based on tests completed 13-18 years before the study ended. This suggests that the onset of Alzheimer's disease can begin many years earlier than expected before symptoms are recognized.
Dr. Doug Brown, Director of Research and Development at the Alzheimer's Association, said: Dementia often causes changes in the brain years before symptoms appear. This study shows that thought and memory may have subtle clues to Alzheimer's disease for up to 18 years before a formal diagnosis is made. Doctors emphasize that these tests cannot accurately predict who will develop dementia, but they can be used to identify people at high risk of developing dementia.
Early warning signs of dementia
Symptoms of dementia can occur in a variety of ways. Cognitive changes can be used to define some, while psychological changes can be used to define others.
The following symptoms are associated with changes in cognitive function.
- Memory decline
- Having a hard time finding words and completing sentences.
- Lack of problem-solving skills.
- Adjustment problem
Below are the signs and symptoms of psychological changes.
- Depressed mood
