Loss of interest or commitment can be an early sign of dementia, dementia that occurs in middle age or old age, which can appear many years ago.
This was revealed in a new medical study in the UK.
A type of dementia, front temporal dementia is more common in people between the ages of 45 and 65, resulting in changes in their behavior, language, and personality.
The Cambridge University study found that one of the most common symptoms of depression is a loss of interest or commitment, which people generally consider depression or lethargy.
Research has shown that loss of interest in things is one of the most common symptoms of this type of dementia, which leads to a decline in quality of life, a decrease in the struggle to survive.
The researchers said that this symptom may appear many years before the onset of the disease and that treatment at this point may also prevent dementia.
Front temporal dementia is often genetic and family history was discovered in one-third of patients.
The study, published in the Journal of the Alzheimer's Association, included 304 healthy people with a gene that causes this type of dementia.
These people were tested for many years and no one was diagnosed with dementia and most of the people involved in the study did not even know if they had that particular gene.
The researchers took different behaviors, memory tests and MRI scans of the brain.
"After years of surveying people, we discovered that people becoming more careless in their daily lives and losing interest in hobbies predict changes in brain function. We shrink these parts of the brain," he said. Looks like they support commitment and move forward and it happens many years before dementia.
A study published in the medical journal Neurology in August found that people who experienced dizziness after sitting up suddenly had a higher risk of developing dementia than others.
The study looked at whether orthostatic hypotension could predict an individual's risk of developing dementia.
In orthostatic hypotension, a person's blood pressure suddenly drops significantly when they stand up and there can be several reasons for this, the most common symptom of which is dizziness while standing.
The study included more than 2,000 people with an average age of 73, and the researchers looked at them for five years.
The researchers instructed the men to complete their blood pressure tests and a brain test while standing in Pune during various experiments.
There are two ways to check blood pressure. One is the pressure of the arteries that is caused by the heart beating and filling, while the other is the expansion or pressure of the arteries when the heart rests between heartbeats.
A healthy blood pressure level in an individual is considered to be less than 120 contractions and 80 dilatations.
In this study, an individual was diagnosed with orthostatic hypotension, whose blood pressure was found to be equal to or greater than 15 contractions and 7 expansions when standing after sitting.
The research team then looked at whether the individuals had been diagnosed with dementia over a 12-year period, based on low scores on medication, hospital records, or tests of brain function.
Of the 309 people in the study, they had orthostatic hypotension and 462 were diagnosed with dementia, for which various factors were taken into account.
The research team found that people with orthostatic hypotension had a 40 percent higher risk of dementia than others.
The research team said the study was observational and did not prove that orthostatic pituitary causes dementia, but there could be several possible explanations for the relationship between the two, including a reduction in blood flow to the brain.
The results may also be limited because the diagnosis of dementia was not based on the formal and clinical analysis.
