Strategies To Clear Brain Fog Post-Stroke

Experiencing brain fog after a stroke is common, and it can last for months or even years. This phenomenon is known as poststroke acute dysexecutive syndrome (PSADES), and it occurs due to tissue death within the brain, causing cognitive decline. While the physical effects of a stroke may be more immediately concerning, the mental fog that follows can be highly disruptive to daily life, affecting memory, concentration, and the ability to follow conversations. Fortunately, PSADES tends to improve over time as the brain rewires itself and forms new pathways for relaying signals.

Poststroke acute dysexecutive syndrome (PSADES)

The condition typically improves gradually over several months as the brain rewires and forms new pathways for relaying signals. However, the recovery process can be long and slow, and the need for assistance may persist. Treatments such as therapy and repetitive actions can aid in recovery by helping the brain learn to send signals more efficiently.

While the symptoms of PSADES tend to improve over time, the underlying neural mechanisms are not yet fully understood. Further studies are needed to determine how the disruption in network dynamics results in cognitive dysfunction and to develop more effective treatments.

Neural sluggishness

Brain fog can occur after a stroke, even a minor one, due to diminished neural activity and processing in the brain. This can lead to cognitive dysfunction, known as poststroke acute dysexecutive syndrome (PSADES). PSADES is characterised by dead tissue lesions in the brain caused by the stroke, which disrupt the cognitive network and result in global dysfunction. This means that even a small lesion can affect the brain's ability to function properly and can lead to symptoms such as memory issues, confusion, and difficulty concentrating.

The good news is that PSADES tends to improve over several months as the brain has an incredible ability to "rewire" itself and create new pathways for signal relay. This process can be facilitated by repetitive actions, such as therapy, which help the brain learn how to send signals more efficiently. Sleep is also an important factor in brain health and can help reduce neural sluggishness. It is recommended to aim for 7 to 9 hours of sleep per night and create a consistent sleep schedule.

In addition to rest and therapy, there are other ways to improve neural sluggishness after a stroke. Maintaining a healthy blood circulation system is important as it ensures that the brain receives adequate blood and oxygen. This can be supported by regular exercise and a healthy diet. Additionally, certain natural remedies and traditional Chinese medicine techniques, such as acupuncture, have been suggested to improve cognition and reduce brain fog.

While the exact mechanisms of neural sluggishness after a stroke are not fully understood, it is clear that the brain has a remarkable capacity for recovery. With time, patience, and the implementation of healthy habits, it is possible to improve cognitive function and reduce the effects of neural sluggishness.

Repetitive actions

"Brain fog" is a term used to describe certain symptoms that affect your ability to think. Symptoms include feeling confused, disoriented, scattered, dull, grogy, and unable to focus, remember things, or put your thoughts into words. Brain fog is a common occurrence after a stroke, and it can be quite debilitating.

Engaging in repetitive actions is crucial to overcoming brain fog after a stroke. The brain has an incredible ability to "rewire" itself and create new pathways for signal relay, but this process takes time and repetition. Here are some repetitive actions that can help:

Therapy:

Therapy is an essential part of stroke recovery. It can help improve cognitive function and address any mental health issues that may arise due to the stroke. Working with a therapist can provide you with new ways to handle tasks that you find challenging.

Exercise:

Physical exercise, such as walking, swimming, or any other enjoyable activity, can help stimulate the brain and promote neuroplasticity. It also improves blood flow to the brain, providing it with the oxygen and nutrients it needs to heal and function optimally.

Mental stimulation:

Engaging in mentally stimulating activities is crucial for brain recovery. This includes activities such as crossword puzzles, word searches, reading, writing, learning a new language or instrument, and playing games like chess or cards. These activities help strengthen neural connections and improve cognitive function.

Routine and structure:

Establishing a daily routine can be beneficial. Structure provides a sense of familiarity, which can reduce confusion and disorientation. A routine that includes mental and physical exercises, healthy eating, and adequate sleep can promote brain health and reduce brain fog.

Healthy habits:

Adopting healthy habits can improve overall brain function and reduce inflammation, which is a common issue after a stroke. This includes eating a healthy diet rich in omega-3s, antioxidants, and anti-inflammatory foods, as well as getting regular exercise, reducing stress, and getting adequate sleep.

It is important to remember that recovery from a stroke takes time, and the effects of repetitive actions may not be immediately noticeable. However, with patience and persistence, these actions can help improve brain fog and promote overall brain health and recovery.

Sleep

After a stroke, the brain is healing and repairing, and sleep is crucial for this process. During sleep, the brain can form new pathways and consolidate memories, which can help to improve cognitive function. Sleep also helps to reduce inflammation and promotes the removal of waste products, which can support the healing process.

Some people may experience disruptions in their sleep after a stroke, such as insomnia or sleep apnea. It is important to address these issues and improve sleep quality. Maintaining a consistent sleep schedule, where you go to bed and wake up at the same time each day, can help regulate your body's internal clock and improve sleep. Creating a relaxing bedtime routine and a calm sleep environment can also promote better sleep. This may include avoiding caffeine and alcohol, especially close to bedtime, and limiting screen time before bed.

Additionally, staying active during the day and engaging in regular physical activity can improve sleep quality. Mild to moderate exercise can help to tire the body and promote more restful sleep. However, it is important to avoid strenuous activity close to bedtime, as this may interfere with your sleep.

For some people, stroke recovery may include therapy or rehabilitation, which can be tiring. Prioritising rest and listening to your body's needs are essential steps in the healing journey. Napping during the day can also be beneficial, especially if you are experiencing fatigue or sleep disturbances at night. However, be mindful of the length and timing of naps to avoid disrupting your nighttime sleep.

Remember that everyone's recovery journey is unique, and it is always best to consult with your doctor or healthcare team for personalised advice and recommendations regarding sleep and stroke recovery.

Magnetoencephalography (MEG)

MEG is often used in conjunction with other brain activity measurement techniques, such as electroencephalography (EEG) and functional magnetic resonance imaging (fMRI). One of the main advantages of MEG over these other techniques is its superior spatial resolution. This is because magnetic fields are less distorted by the skull and scalp than electric fields, allowing for more accurate localisation of neural activity. MEG is also able to detect intracellular currents, whereas EEG is sensitive to extracellular currents.

In a clinical setting, MEG can be used to detect and localise pathological activity in patients with epilepsy and to localise eloquent cortex for surgical planning in patients with brain tumours or intractable epilepsy. MEG has also been used to study cognitive processes such as vision, audition, and language processing in fetuses and newborns, as well as in patients with psychiatric disorders and traumatic brain injuries.
