What is it?

Cognitive disorders are a part of the neurocognitive disorder classification in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V). Cognitive disorders are defined as any disorder that significantly impairs the cognitive function of an individual to the point where normal functioning in society is impossible without treatment. Some common cognitive disorders include:

• Dementia
• Developmental disorders
• Motor skill disorders
• Amnesia
• Substance-induced cognitive impairment

Cognitive disorder signs vary according to the particular disorder, but some common signs and symptoms overlap in most disorders. Some of the most common signs of cognitive disorder include:

• Confusion
• Poor motor coordination
• Loss of short-term or long-term memory
• Identity confusion
• Impaired judgment

The ability to engage in sexual activity and better cognitive functioning are both associated with better health.

Greater cognitive function has been associated with better physical and psychological health, and greater quality of life among older adults.

Some studies show that men with dementia have lower testestrone levels, which has been associated with lower sexual desire and higher rates of sexual dysfunction concomitant with cognitive decline.
