Deans' stroke musings: Can anxiety damage the brain?

Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

Can anxiety damage the brain?

Is your doctor even testing your anxiety? Or treating it? Your doctor has probably massively increased your anxiety by not giving you any information on how well you will recover. Because they will spout off the fuckingly stupid statement, 'All strokes are different, all stroke recoveries are different'. My doctor totally sidestepped this problem because he didn't bother to tell me I had a stroke or any prognosis on recovery, he told me I had a CVA, I had to ask what that was.

Abstract

PURPOSE OF REVIEW:

Stress exacerbates mental illnesses such as depression but also appears to increase risk of dementia, suggesting a common mechanism for development of stress-induced affective and cognitive impairment. The purpose of this review is to address the question of whether anxiety 'damages' the brain, and to identify potential mechanisms for the link between stress and neuropsychiatric illness.

RECENT FINDINGS:

Anxiety disorders are associated with alterations in fear neurocircuitry such that 'bottom-up' processes in the amygdala which respond to threat are exaggerated, and regulation of these processes by the prefrontal cortex (PFC) and hippocampus is impaired. Chronic stress exposure similarly alters fear neurocircuitry by enhancing amygdalar functioning while causing structural degeneration in the PFC and hippocampus thereby inhibiting PFC/hippocampus control over the stress response. Pharmacological (e.g., antidepressant medications) and nonpharmacological interventions (cognitive-behavioral therapy, exercise) may reverse stress-induced damage in the brain.

SUMMARY:

Pathological anxiety and chronic stress lead to structural degeneration and impaired functioning of the hippocampus and the PFC, which may account for the increased risk of developing neuropsychiatric disorders, including depression and dementia. Longitudinal studies are needed to determine whether reversal of stress-induced brain changes by interventions such as cognitive-behavioral therapy can reduce risk of neuropsychiatric illness.
