Anxiety Is Linked To These Common Mental Health Problems By Neurocircuitry

Anxiety Is Linked To These Common Mental Health Problems By Neurocircuitry post image

Anxiety is a normal part of everyday life, but when anxiety starts to interfere with everyday life it can become a more serious problem.

Stress and anxiety have been linked to the same neurocircuitry in the brain as depression and dementia.

The new study suggests people need to find ways to reduce chronic stress or they could be putting themselves at increased risk of mental health problems.

Neuroscientists have found there is an extensive overlap between neurocircuitry for anxiety, depression and dementia.

Dr. Linda Mah, who led the study, said:

“Pathological anxiety and chronic stress are associated with structural degeneration and impaired functioning of the hippocampus and the prefrontal cortex (PFC), which may account for the increased risk of developing neuropsychiatric disorders, including depression and dementia.”

Experiencing anxiety is a normal part of everyday life.

But, when anxiety starts to interfere with everyday life, it can become a more serious problem.

Chronic anxiety has also been linked to problems with memory and other health difficulties such as metabolic and immune disorders.

A previous study by Dr Mah and colleagues found that anxiety doubled the risk of developing Alzheimer’s disease:

“Canadian researchers examined 376 people between the ages of 55 and 91 with ‘mild cognitive impairment’, and their chances of going on to develop Alzheimer’s disease


The results showed that for people with mild anxiety symptoms, the chances of developing Alzheimer’s increased by 33%, for those with moderate anxiety it was 78% and for those with severe anxiety, the risk increased by 135%.

While depression has already been identified as a risk factor for developing Alzheimer’s, this is the first study to implicate anxiety separately.”

Dr. Mah said:

“Looking to the future, we need to do more work to determine whether interventions, such as exercise, mindfulness training and cognitive behavioural therapy, can not only reduce stress but decrease the risk of developing neuropsychiatric disorders.”

The study was published in the journal Current Opinion in Psychiatry (Mah et al., 2016).
