More than “Brain Fog”: Cognitive Dysfunction and the Role of Occupational Therapy in Long COVID

Long COVID is a disabling condition which affects occupational performance and quality of life. It interferes with activities of daily living, work, and many meaningful life roles. Cognitive dysfunction is a frequently reported symptom, yet it is commonly overlooked. It is important that cognitive activity is considered when working with people with long COVID, particularly when identifying triggers of post exertional symptom exacerbation. There are many potential mechanisms that could be driving cognitive dysfunction in long COVID including neuroinflammation, viral persistence, vascular damage, and orthostatic intolerance. It is important to consider these to help guide intervention. The purpose of this clinical perspective is to highlight the debilitating impact of cognitive dysfunction in those with long COVID and share the key role of occupational therapists in this area. Cognitive dysfunction may be missed on standardized assessments as they may not be sensitive enough due to the episodic nature of symptoms. Occupational therapists can play a key role in this area as they are experts in assessing occupational performance and in providing safe cognitive assessment and rehabilitation.
