A nurse is teaching a nursing student about secondary Neurocognitive Disorders. Which of the following are the causes of secondary Neurocognitive Disorders? Select all that apply.

A. Contracture: Contracture refers to the permanent tightening of muscles or joints and is not directly related to neurocognitive disorders. It is a physical condition rather than a cause of cognitive impairment.

B. Cerebral trauma:  Cerebral trauma, such as traumatic brain injury, can lead to secondary neurocognitive disorders due to direct damage to brain tissues and subsequent cognitive impairments.

C. Fever: Severe or prolonged fever can be associated with secondary neurocognitive disorders, especially if it leads to complications like encephalitis or severe metabolic disturbances.

D. Human Immunodeficiency Virus (HIV): HIV can lead to secondary neurocognitive disorders due to the direct effects of the virus on the brain and the resultant immune deficiency, which can allow opportunistic infections that affect cognitive function.

E. Huntington's disease: Huntington's disease is a primary neurodegenerative disorder characterized by the progressive breakdown of nerve cells in the brain. It directly causes neurocognitive decline due to genetic mutations and is considered a primary neurocognitive disorder rather than a secondary one. Secondary neurocognitive disorders are typically the result of another primary condition or external factor such as trauma or infection, rather than a primary neurodegenerative disease.
