Verified step by step guidance

1. Understand the key term 'disorder of cognition' which refers to conditions that primarily affect mental processes such as memory, attention, problem-solving, and other intellectual functions.
2. Recognize that brain abnormalities often cause cognitive disorders because they directly impact the brain's structure or function.
3. Review the options given: Major depressive disorder, Obsessive-compulsive disorder, Generalized anxiety disorder, and Dementia, and consider which primarily involves cognitive impairment due to brain abnormalities.
4. Recall that Major depressive disorder, Obsessive-compulsive disorder, and Generalized anxiety disorder are primarily mood or anxiety disorders, which affect emotions and behavior rather than cognition directly.
5. Identify Dementia as a disorder characterized by a decline in cognitive function caused by brain abnormalities, making it the correct answer to the question.
