Cognitive rigidity

Cognitive rigidity is present in many mental health disorders, including obsessive-compulsive disorder, major depression, and autism spectrum disorder. 

Research shows that cognitive flexibility depends on the network of the frontal lobe and "striatal" brain regions. 

• The brain's frontal area is involved in higher cognitive processes, such as decision-making and problem-solving. 
• The striatum area is related to reward and motivation.
