Cognitive disorders are not a normal part of aging, although some age-related cognitive decline can occur. When cognitive impairment interferes with daily functioning, work performance, or social interactions, it is considered a cognitive disorder.

 

These conditions may result from:

• Neurological damage

• Brain injuries

• Genetic factors

• Infections

• Mental health conditions

• Chronic stress or substance abuse

 

Types of Cognitive Disorders

 

Cognitive disorders can be broadly classified based on severity, cause, and progression.

1. Neurodegenerative Cognitive Disorders

These worsen over time due to progressive brain damage.

• Alzheimer’s disease

• Parkinson’s disease dementia

• Huntington’s disease

2. Vascular Cognitive Disorders

Caused by reduced blood flow to the brain.

• Vascular dementia

• Post-stroke cognitive impairment

3. Developmental Cognitive Disorders

Present from early life and affect learning and intellectual abilities.

• Intellectual disability

• Learning disorders

4. Acquired Cognitive Disorders

Occur due to injury or illness later in life.

• Traumatic brain injury (TBI)

• Cognitive impairment due to infections or tumors

5. Mild Cognitive Disorders

Early-stage conditions that may or may not progress.

• Mild Cognitive Impairment (MCI)

 

 

Cognitive Disorder Examples

 

Some commonly diagnosed cognitive disorders include:

• Alzheimer’s disease – Progressive memory loss and confusion
