A potential breakthrough in early detection of Alzheimer’s disease could help individuals understand their risk long before symptoms appear. A neurologist has highlighted a specific blood biomarker that may offer insights into the likelihood of developing this condition which is one of the leading causes of Dementia worldwide.
Alzheimer’s disease gradually affects memory thinking ability learning capacity and organisational skills. It is most commonly diagnosed in people over the age of 65 and currently has no cure or method to reverse its progression. Because of this early detection and prevention strategies are considered extremely important.
According to Dr Ayesha Sherzai, a long term study involving 2766 women with an average age of 70 tracked a specific blood biomarker known as PTA27 over a period of up to 25 years. Researchers analysed how this marker related to the development of mild cognitive impairment and dementia over time.
The findings suggested that higher levels of this biomarker were strongly associated with an increased risk of developing dementia. Each increase in the measured level was linked to a significantly higher likelihood of cognitive decline. Individuals in the highest range of the biomarker showed a substantially greater risk compared to those in the lowest range.
The association appeared to be stronger among women over 70 and individuals carrying certain genetic risk factors. Additionally the study observed that hormone related factors such as combined estrogen and progesterone therapy may influence the overall risk.
While the research highlights a strong connection between the biomarker and dementia risk it does not yet prove direct causation. The test is still under development and is not widely available for clinical use at this stage.
Steps to Reduce Alzheimer’s Risk
Even as research continues experts emphasise the importance of lifestyle choices in lowering the risk of Alzheimer’s. Evidence based recommendations include maintaining cardiovascular health eating a balanced diet rich in green vegetables engaging in regular physical activity managing stress levels and staying socially and mentally active.
Experts stress that prevention remains one of the most powerful tools currently available in reducing the chances of cognitive decline later in life.
