Is Alzheimer’s Disease Related To Depression And Anxiety Disorders?

With the inclining mental health issues, researchers suggest people should reveal more about psychotic problems as it aids in their recovery. A preliminary study ensures that depression and anxiety give rise to Alzheimer’s disease (AD). People with a history of anxiety and depression may encounter memory and thinking issues, ultimately leading to AD. 

The research findings state that amongst 1,500 Alzheimer’s patients, 43% are the victim of depression, and approximately one-third are the victim of anxiety disorders. Moreover, some people who are patients of dementia may develop AD without any history of depression or anxiety disorder.

Digging Up To Unveil Alzheimer’s 

Researchers are on the urge to discover if AD comes hand in hand with depression or anxiety. Dr. Zachary Miller researched Alzheimer’s disease (AD). Dr. Zachary Miller is an assistant professor at the University of California, San Francisco.

Miller was concerned that depression and anxiety patients were more prone to developing AD. Moreover, he was doubtful if the symptoms of anxiety and depression were an early sign of the progress of dementia disease. 

Dr. Zachary Miller leans toward the latter explanation. However, this research cannot give any evidence that depression or anxiety disorders may contribute to dementia. 

In an online annual meeting, held from April 17 to 22, Miller presented the research results at the American Academy of Neurology. After the preliminary consideration of the studies, they get published in a peer-reviewed journal.

The occurrence of AD concurrent with various mental health disorders is not an innovation. Numerous studies conducted in the past have supported that there is an association between depression and a greater risk of dementia, though lack causes and effects. 

What Pushes A Person Into Alzheimer’s

Few studies view the correlation between AD and other mental health disorders, for instance, anxiety. So Miller and his colleagues screened 1,500 Alzheimer’s patients, for any history of mental-disorder. Moreover, these patients may have anxiety, depression, bipolar disorder, post-traumatic stress disorder, and schizophrenia before Alzehmir. 

Their study suggests about 43% of patients had a history of depression. Moreover, only 32% suffered from anxiety, and the remaining disorders were uncommon. 

Miller suggests that some Alzheimer’s patients showed mental health symptoms in the recent past and were diagnosed with AD within two years. However, some patients were diagnosed with Alzheimer’s after ten years of the onset of mental health symptoms.  

In a nutshell, the research found that people with a history of depression or anxiety were victims of AD at a younger age. Moreover, the study shows that people with psychiatric conditions were at a higher risk of dementia. More precisely, they were three years younger at diagnosis in comparison to those without any history of the psychiatric situation. 

Inclining Confusion

Dr. John Morris supports the idea that the onset of mental health symptoms could be an early indication of AD to some extent, as exceptions are always there. 

Dr. John Morris is the director of the Knight Alzheimer’s Disease Research Center at Washington University School of Medicine. He put forward his recent research. In his research he found out that his volunteers had not developed dementia although they had AD biomarkers in their brain.

Thus, he concludes that no evidence can relate to depression, dementia, and AD. Moreover, there is a lack of scientific evidence that can confirm that depression leads to dementia. 

John Morris was not involved in the recent research. He said that people with depression or anxiety disorders seek medical care on time before catching dementia. 

However, there is uncertainty whether medication plays any role or not. Morris said the drugs given to psychiatric patients are capable of exacerbating symptoms, worsening thinking and memory problems, leading to an earlier screening of AD. 

According to Morris, this study opens the gate to numerous research, as the findings give rise to more questions than sorting previously aroused questions.
