How does stress affect cognitive functioning?
Psychological stress can affect cognitive function in the short-term (e.g., as when an individual’s thoughts are occupied with an argument that happened earlier in the day resulting in reduced ability to pay attention to, keep track of, or remember steps in the task at hand) as well as over the long-term (e.g., as when …

What is reduced cognitive functioning?
What is cognitive impairment? Cognitive impairment is when a person has trouble remembering, learning new things, concentrating, or making decisions that affect their everyday life.
Does stress cause cognitive decline?
Repeated Stress Causes Cognitive Impairment by Suppressing Glutamate Receptor Expression and Function in Prefrontal Cortex.
How does stress impact a child’s cognitive abilities?
Children who grow up in stressful environments often have elevated levels of “the stress hormone” cortisol, which can impair cognitive development. New research shows that some children growing up with adversity actually have low levels of cortisol, which is also linked to compromised cognitive functioning.
How does stress affect the brain’s function to perceive and handle problems especially in traumatic experiences?
Answer: Brain areas implicated in the stress response include the amygdala, hippocampus, and prefrontal cortex. Traumatic stress can be associated with lasting changes in these brain areas. Traumatic stress is associated with increased cortisol and norepinephrine responses to subsequent stressors.
Why do you think stress can affect the brain’s function to perceive and handle problems especially in traumatic experiences?
Stress results in acute and chronic changes in neurochemical systems and specific brain regions, which result in longterm changes in brain “circuits,” involved in the stress response. Brain regions that are felt to play an important role in PTSD include hippocampus, amygdala, and medial prefrontal cortex.
What are the symptoms of excessive stress?

What factors are important in maintaining cognitive functioning in older adults?
Behavioral factors including exercise, smoking, and volunteering are modifiable factors that may be used in strategies to ensure optimal cognitive function in old age.
