A situation where a person has difficulty switching between tasks or thoughts, as well as adapting their behavior to a changing environment. Cognitive flexibility – the ability to adapt to changes and new situations, as well as switch between thinking strategies or actions as needed. With disorders of executive functions, a person is prone to rigidity, insists on the only right decision, or has difficulty adapting to unexpected situations. This deficit leads to frequent frustration, difficulty solving problems, and an inability to change behavior to meet new demands.
