How Cognitive Therapy Helps Stroke Survivors

Stroke is among the top causes of severe long-term disability globally. A lot of individuals who suffer a stroke end up with thinking and memory difficulties. These difficulties may make everyday activities challenging. This not only affects the individual who suffered the stroke but also the people around them. Studies reveal that nearly 60% of survivors of a stroke experience cognitive impairment in their initial year of recovery. Fortunately, those individuals with mild symptoms in these regions stand the best chance of improvement. A stroke also affects mood and feelings; it is not just a reaction to a potentially life-threatening event.

The functions affected by a stroke depend on the area of the brain that has been injured, varying from speech and movement to thinking and emotions. Manic feelings may be caused by damage to the right temporal lobe, while depression is associated with damage to the left. Frontal lobe damage often changes behaviour and emotional processing. Strokes can ruin lives. In addition to the physical impact, they often leave individuals with cognitive issues that make everyday activities difficult. That is why we require evidence-based treatments and team-based strategies to enable stroke survivors to regain their independence and get back to work and daily life.

Cognitive Impairments By Stroke

A stroke significantly affects cognitive function, including impairments in memory, attention, problem-solving, perception, concentration, vision, and planning.

Learning and Memory Loss Impairment: Learning disabilities are differences in a person's brain that can affect their ability to read, write, speak, perform math, and handle other similar tasks. Memory loss is an unusual forgetfulness. You may not be able to remember new events, recall one or more memories of the past, or both. The loss of memory is temporary, but it can persist, and depending on the reason, it may worsen over time.
Concentration and Attention Problems: Concentration and attentional deficits are manifested in various impairments, ranging from impaired focus and distractibility to poor error control, problems with multitasking, mental slowness, and mental fatigue. Higher-order abilities, such as language and memory, are also adversely affected by attentional impairments, as they serve as mediators for other cognitive processes.
Problem-Solving and Planning Impairment: Problem-solving and planning are key components of executive function. It encompasses everything that enables us to plan, make choices, and determine when we must take action. It also includes how we monitor the world around us and adjust our thoughts and actions accordingly.
Vision Impairment: One side of the brain is affected by most strokes. Because the nerves from both eyes pass through the brain jointly, both eyes are impacted. The left-side vision in each eye may be affected if there is injury to the right side of the brain. It is uncommon for a stroke to affect both sides of the brain. It can cause blindness when it does occur.

How Cognitive Rehab Works

The goal of cognitive rehabilitation is to enhance memory, and it is generally believed to incorporate four approaches:

Restorative Approach: The goal of the healing approach is to restore pre-stroke functioning. Drill and practice exercises have been commonly managed with word or list learning or paragraph recall tasks, suggesting that from-memory repetition with encouragement may be an effective treatment for memory problems. Significant improvements in memory ability (to hold or do something), understanding of memory problems, successfully dealing with daily memory problems, and decreased fear and stress about memory functioning. If memory is an issue, you can play games that require you to remember lists or patterns. Over time, these exercises help the brain form new connections, so it's smarter, not harder.
Specific knowledge acquisition approach: This involves teaching knowledge related to the person's everyday life in clearly stated domains (e.g., names of hospital staff or remembering when and how to complete household duties) without expecting an improvement in general memory functioning. These approaches could be beneficial for patients with severe memory disabilities, who may experience significant difficulties, delays, or other problems with tasks that require clear memory. However, to address this limitation, some suggest that patients may be able to quiz themselves or be questioned by family members on learned information (e.g., phone numbers or names), or be tested through the use of booklets, timers, or sliders.

Compensatory Rehab: The compensatory approach involves using strategies and tools that mitigate the impact of memory problems in daily life and enhance daily functioning, without expecting improvement in memory functioning. There has been some success in applying internal and external memory aids to improve the daily functioning of individuals with memory impairments. It has been suggested that internal aids are better suited for individuals with mild memory impairment. In contrast, external memory aids may be more suitable for those with moderate to severe impairment.
Holistic approach: The holistic approach addresses the emotional, social, and functional consequences of the condition. Thus, improving self-awareness through education and feedback within the therapeutic setting while addressing the emotional, social, and behavioural consequences can promote improved functional outcomes in these areas. The evidence regarding the improvement of cognitive functions is more mixed; reintegration within community settings and improvements in social participation are undeniably beneficial outcomes of the holistic approach.

Techniques Used in Cognitive Rehabilitation for Stroke Patients

Cognitive rehabilitation is founded on the theory of experience-dependent neuroplasticity (rearrangement of brain cells involves the brain's ability to absorb information and adaptive structural and functional changes), which states that the human brain is not a static organ that may physically change when subjected to challenges or workouts. After being exposed to richer surroundings, brain pathways and synapses may undergo these alterations. Cognitive remediation creates such a rich environment.

Examples of strategies used during cognitive rehabilitation:

Neurofeedback or electroencephalogram (EEG) biofeedback.
Use flashcards, AI, or GPS devices for task organisation.
Virtual Reality.
Speech therapy.
Attention Processing Training (APT).
Computer-assisted training program.
Problem-solving games.
Motor Relearning Task (MRP).
