The Lingering Exhaustion: Understanding Post-Stroke Fatigue

Delving into the cause and impact of post-stroke fatigue.

Key points

  • Post-stroke fatigue plays a significant role in physical and cognitive rehabilitation outcomes.
  • Research indicates that approximately 48 percent of stroke survivors experience symptoms of fatigue.
  • Recognising both physical and mental signs of fatigue is essential to finding effective coping strategies.

Post-stroke fatigue (PSF) is a debilitating condition that impacts the well-being and recovery progress of stroke survivors. Studies indicate that approximately 48 percent of stroke survivors experience PSF (1), making it a prevalent and distressing consequence of a stroke.

What Is Post-Stroke Fatigue?

Post-stroke fatigue is characterised by prolonged tiredness, low energy, and generalised exhaustion. It is essential to recognise the intricate nature of PSF since it differs from typical fatigue and can adversely impact the body, mind, and emotions, and most notably, it is not resolved by rest or sleep.

While physical fatigue may manifest as a sense of bodily weakness, heaviness, or weariness, mental fatigue can lead to difficulties in concentration, cognitive processing, and emotional regulation. This is due to the brain's injury from the stroke, which disrupts the intricate network of neural circuits that are responsible for regulating energy levels and cognitive function, leading to the emergence of chronic fatigue (2).

The combination of physical and mental fatigue can influence a stroke survivor's participation in rehabilitation, social engagements, and personal hobbies. This often leads to frustration and reduced motivation.

How Post-Stroke Fatigue Impacts Recovery

Post-stroke fatigue can delay cognitive, language, and physical recovery during stroke rehabilitation. The persistent exhaustion associated with PSF can compromise primary cognitive domains such as attention, memory, and executive functions, making it challenging to engage in necessary rehabilitation exercises.

Additionally, PSF can interfere with verbal expression and comprehension, making participation in speech and language therapy a difficult task and slowing down language recovery. Furthermore, reduced energy levels can lead to ineffective physical therapy sessions, delaying improvements in mobility and prolonging the rehabilitation process (3).

During the recovery journey, fatigue can manifest and persist for an extended period, influenced by several factors, such as pre-existing conditions and the location of the stroke lesion. For instance, research has shown that individuals with right thalamic strokes are particularly susceptible to experiencing PSF symptoms in the late stages of recovery (4).

Further studies have also shown that fatigue is connected to other common issues after a stroke, like depression, anxiety, and cognitive function (5). This highlights how these challenges are linked and the importance of understanding all factors that impact the recovery journey.

Strategies to Cope with Post-Stroke Fatigue

When dealing with post-stroke fatigue, it is essential to adopt effective coping strategies that allow individuals to manage their symptoms; these may include, for instance, prioritising and pacing activities, setting achievable goals, and taking regular breaks to conserve energy. It is vital to listen to the body, acknowledge the need for rest, and be open to adjusting daily routines accordingly.

Implementing cognitive strategies is crucial in addressing PSF, especially in relation to memory and concentration difficulties. Utilising aids such as calendars and reminders can be beneficial. Engaging in mentally stimulating activities like puzzles and reading can effectively combat mental fatigue and enhance cognitive well-being.

Engaging in physical activity might appear counterintuitive when dealing with PSF, but it can be a valuable tool for managing symptoms. Gentle activities such as walking, yoga, or swimming can progressively increase physical endurance and counteract the impacts of fatigue (6).

Although post-stroke fatigue may present various physical and mental obstacles, by understanding this condition and developing coping mechanisms, it is possible to ignite a spark of renewed vitality and have a bright future after a stroke.
