Depression After Stroke can be Prevented by Tai Chi

Tai chi holds the potential to reduce depression, anxiety and stress along with improvement sleep in people after they had stroke, as per a study presented at EuroHeartCare - ACNAP Congress 2021, an online scientific congress of the European Society of Cardiology (ESC).1

Almost one-third of stroke survivors suffer from depression and are linked with greater disability and mortality rates. Anxiety, stress, and poor sleep are also frequently reported as post-stroke consequences.

How to Deal with a Stroke - Signs - Symptoms - Risk Factors - Prevention
Stroke is a brain attack, which occurs when the blood supply to the brain is interrupted. It affects all age groups; according to the WHO, 15 million people are affected by stroke annually.

‘Tai chi holds the potential to reduce depression, anxiety, and stress along with improvement in sleep among post-stroke survivors. However further analysis is required to interpret the benefits of tai chi for a larger group of people post-stroke. ’

Tai chi is a type of exercise that focuses on releasing tension in the body, incorporating mindfulness and imagery into movement, increasing awareness and efficiency of breathing and promoting overall relaxation of body and mind.

"Mind-body interventions are commonly used among adults to lessen depressive symptoms. Tai chi practice allows the individual to quiet the mind by dwelling in the present and setting aside unnecessary negative emotions, such as depression," says study author Dr. Ruth Taylor-Piliae of the University of Arizona, Tucson, US.

Stroke – Early Warning Signs - Risk Factor - Rehab - Treatment
Stroke can cause permanent disability and it is important to recognize its early warning signs to stop its progress. Early warning signs of stroke include sudden weakness of facial muscles.

The small study enrolled 11 stroke survivors (55% were men) who reported depression symptoms with an average age of 70 years to examine the feasibility of tai chi in them. The tai chi intervention classes (24 basic movements from the Wu style of tai chi) were given to all the stroke survivors three times each week, for a total of eight weeks (shortened duration due to the COVID-19 pandemic).

Standardized questionnaires were used to assess the symptoms of depression, anxiety, and stress. Sleep (percentage of time spent sleeping) was assessed during night-time using a triaxial accelerometer.

Hemiplegia - Causes, Symptoms, Diagnosis, Treatment and Prevention
Hemiplegia is a condition that is characterized by paralysis of one half of the body, usually due to a brain lesion on the opposite side. It may be congenital (cerebral palsy) or acquired later in life due to illness.

It was found that there was a significant reduction in symptoms of depression, anxiety, and stress after just eight weeks of tai chi when compared to baseline, along with better sleep efficiency, less wakefulness after sleep onset, and less time awake.

The study also measured lower activity of the oxidative stress markers after the intervention in the blood samples collected from the patients. However, there were no significant changes seen in any of the inflammatory markers.

Snoring Symptom Evaluation
People, who normally do not snore, tend to do so after a bout of drinking, viral infections or after taking certain medications.

"Our ultimate goal is to see whether tai chi lowers depressive symptoms in stroke survivors and also improves biochemical markers associated with depression. The results of this feasibility study should be interpreted with caution because of the small sample size and lack of a control group. More research is needed before recommendations can be made about tai chi for people who have had a stroke. We hope to do a randomised trial with a 12-week tai chi intervention in a larger group of patients," says Dr. Taylor-Piliae.
