Impaired decision-making and time perception in individuals with stroke: Behavioral and neural correlates

Area of Science:

• Neuroscience
• Cognitive Psychology
• Neurology

Background:

• Stroke frequently leads to deficits in decision-making and timing.
• Neural circuits involving the cerebellum and prefrontal cortex are implicated in these functions.
• Understanding these impairments is crucial for patient recovery and rehabilitation.

Purpose of the Study:

• To identify knowledge gaps regarding decision-making and timing deficits in stroke patients.
• To enhance the understanding of the mechanisms underlying these impairments.
• To explore the neural circuit connections between the prefrontal cortex and cerebellum in timing.

Main Methods:

• A comprehensive literature review was conducted.
• 65 relevant studies were synthesized.
• Neurobiological modalities, cognitive tasks, and motor control were analyzed.

Main Results:

• Timing processes are critical for cognitive task performance in stroke survivors.
• The cerebellum and prefrontal cortex play significant roles in decision-making and time perception.
• Impaired decision-making in stroke impacts executive functions and time interval interpretation.

Conclusions:

• Decision-making and timing impairments are significant consequences of stroke.
• The cerebellum and prefrontal cortex are key brain regions involved.
• Further research is needed to fully elucidate the neurobiological underpinnings.
