Final answer:
Major or Mild Neurocognitive Disorder due to HIV is linked to immune system dysfunction.
Step-by-step explanation:
Major or Mild Neurocognitive Disorder due to HIV is linked to immune system dysfunction. Acquired immune deficiency syndrome (AIDS), caused by the human immunodeficiency virus (HIV), directly targets T cells in the immune system. HIV gains entry through a receptor on T cells and multiplies using the T cell's genetic machinery. This leads to immune system dysfunction and can result in neurocognitive disorders. Patients with HIV/AIDS are at increased risk of developing neurocognitive disorders, such as Mild Neurocognitive Disorder. This is due to the impairment of immune system function caused by the HIV virus.
