Don’t worry, be happy: Stress, anxiety could lead to dementia

Don’t worry – Experts say that chronic stress can wreak havoc on immune, metabolic and cardiovascular systems, and lead to atrophy of the brain’s hippocampus–crucial for long-term memory and spatial navigation. Here’s something so that you start taking stress more seriously. People who suffer from chronic stress and anxiety may be at an increased risk for developing depression and even dementia, says a new study suggests. Experiencing anxiety, fear and stress is considered a normal part of life when it is occasional and temporary, such as feeling anxious and stressed before an exam or a job interview.

However, when those acute emotional reactions become more frequent or chronic, they can significantly interfere with daily living activities such as work, school and relationships, according to researchers at Rotman Research Institute at Baycrest Health Sciences in Canada. Chronic stress is a pathological state that is caused by prolonged activation of the normal acute physiological stress response, which can wreak havoc on immune, metabolic and cardiovascular systems, and lead to atrophy of the brain’s hippocampus –crucial for long-term memory and spatial navigation. Researchers examined recent evidence from studies of stress and fear conditioning in animal models, and neuroimaging studies of stress and anxiety in healthy individuals and in clinical populations. They looked specifically at key structures in the neurocircuitry of fear and anxiety (amygdala, medial prefrontal cortex, hippocampus) which are impacted during exposure to chronic stress.

The researchers noted similar patterns of abnormal brain activity with fear/anxiety and chronic stress — specifically an overactive amygdala (associated with emotional responses) and an under-active PFC (thinking areas of the brain […]
