PATHOGENESIS
• Human immunodeficiency virus (HIV) is a blood-borne, sexually transmissible virus
• The virus is typically transmitted via - Sexual intercourse. - Shared intravenous drug. - Mother-to-child transmission (MTCT): *during the birth process or *during breastfeeding.
![Page 3: Neuropsychiatry and Behavioral Aspect of HIV spectrum Disease](https://reader036.vdocuments.net/reader036/viewer/2022070521/58ef8b661a28aba1118b45a3/html5/thumbnails/3.jpg)
PATHOGENESIS
• Two distinct species of HIV HIV-1 and HIV-2 • HIV-1 originated and transfers from
chimpanzees in central Africa.• HIV-2 is closely related to viruses that infect
sooty mangabeys in western Africa.• Genetically, HIV-1 and HIV-2 are superficially
similar, but each contains unique genes and its own replication .

AIDS DEMENTIA
• The prevalence of AIDS-related dementia, and the AIDS-dementia complex (ADC) varies between 8 and 16% in cases .
• ADC is characterized by cognitive, motor, and behavioral features in advanced cases .
• Highly active antiretroviral therapy (HAART,) minor cognitive motor disorder (MCMD), is common than ADC.
![Page 14: Neuropsychiatry and Behavioral Aspect of HIV spectrum Disease](https://reader036.vdocuments.net/reader036/viewer/2022070521/58ef8b661a28aba1118b45a3/html5/thumbnails/14.jpg)

AIDS DEMENTIA COMPLEX
• Apathy,• Social withdrawal, • Impaired concentration,• Mental and motor slowing.• Motor weakness and clumsiness• Problems with complex sequential mental
activities.
![Page 17: Neuropsychiatry and Behavioral Aspect of HIV spectrum Disease](https://reader036.vdocuments.net/reader036/viewer/2022070521/58ef8b661a28aba1118b45a3/html5/thumbnails/17.jpg)
STAGES OF ADC• Stage 1• In stage 1 (mild), the patient is able to perform all but the
more demanding aspects of work but has unequivocal evidence of functional, intellectual, or motor impairment. Signs or symptoms may include diminished performance on neuropsychological testing. Patient can walk without assistance.
• Stage 2• In stage 2 (moderate), the patient is able to perform basic
activities of self-care but cannot work or maintain the more demanding aspects of daily life. The patient is ambulatory but may require a single prop.
![Page 18: Neuropsychiatry and Behavioral Aspect of HIV spectrum Disease](https://reader036.vdocuments.net/reader036/viewer/2022070521/58ef8b661a28aba1118b45a3/html5/thumbnails/18.jpg)
STAGES OF ADC
• Stage 3• In stage 3 (severe), the patient has major intellectual
incapacity (cannot follow news or personal events, cannot sustain complex conversation, shows considerable slowing of all outputs). Motor disability , walking is usually slowed and accompanied by clumsiness of arms.
• Stage 4• In stage 4 (end stage), the patient is in a nearly
vegetative state. Intellectual and social comprehension. Mute , paraparetic or paraplegic, with urinary and fecal incontinence.
![Page 19: Neuropsychiatry and Behavioral Aspect of HIV spectrum Disease](https://reader036.vdocuments.net/reader036/viewer/2022070521/58ef8b661a28aba1118b45a3/html5/thumbnails/19.jpg)
DELIRIUM
• Delirium is a consequence of - Severe medical illnesses . - Treatment course - With acute, profound cognitive impairment. Behavioural manifestations: Agitation, psychosis . Aggressive behaviour . Mutism Marked withdrawal.
![Page 20: Neuropsychiatry and Behavioral Aspect of HIV spectrum Disease](https://reader036.vdocuments.net/reader036/viewer/2022070521/58ef8b661a28aba1118b45a3/html5/thumbnails/20.jpg)
AFFECTIVE DISORDER
• Grief, as they adjust to living with a terminal illness.
• Dysphoric affect is expected part of this grieving process .
• Organic mood disorder may exist either as a feature of or independent of ADC
• did not respond to conventional antidepressant therapy, but remitted coincidentally with treatment with zidovudine (AZT),
![Page 21: Neuropsychiatry and Behavioral Aspect of HIV spectrum Disease](https://reader036.vdocuments.net/reader036/viewer/2022070521/58ef8b661a28aba1118b45a3/html5/thumbnails/21.jpg)
ANXIETY STATE
• Anxiety disorder is common in groups at high risk for HIV infection irrespective of HIV status.
• Individuals with pre-existing disorder may be at increased risk for exacerbation of symptoms.
![Page 22: Neuropsychiatry and Behavioral Aspect of HIV spectrum Disease](https://reader036.vdocuments.net/reader036/viewer/2022070521/58ef8b661a28aba1118b45a3/html5/thumbnails/22.jpg)
PSYCHOTIC REACTION
• Is a symptom of delirium ,
• from any CNS opportunistic infected CNS, • result of medication used in the treatment.
- Paranoid delusions, - Auditory hallucination. - Manic symptoms - Catatonia .

PAIN SYNDROME
• Polyneuropathy is distal and symmetrical -Occur at all stages of HIV - Occur during serious illness as herpes zoster and advance malignancies. • Characterised by :
-painful, burning dysesthesias.
![Page 24: Neuropsychiatry and Behavioral Aspect of HIV spectrum Disease](https://reader036.vdocuments.net/reader036/viewer/2022070521/58ef8b661a28aba1118b45a3/html5/thumbnails/24.jpg)

![Page 25: Neuropsychiatry and Behavioral Aspect of HIV spectrum Disease](https://reader036.vdocuments.net/reader036/viewer/2022070521/58ef8b661a28aba1118b45a3/html5/thumbnails/25.jpg)
MODIFIED HIV DEMENTIA SCALE
• The scale consists of subsets for memory (eg, recall, registration),
• psychomotor speed, • constructional ability,• concentration.• A total of 12 points can be earned,• and a score lower than 6 points is considered
abnormal. • Takes 10 minutes to administer
![Page 26: Neuropsychiatry and Behavioral Aspect of HIV spectrum Disease](https://reader036.vdocuments.net/reader036/viewer/2022070521/58ef8b661a28aba1118b45a3/html5/thumbnails/26.jpg)
ANTIRETROVIRAL AND OTHER THERAPIES
• highly active antiretroviral therapy (HAART) is the treatment for HIV-related cognitive disorders.
• Aggressive early treatment of patients with HIV disease with antiviral medications and early suppression of viral replication prevents most of the devastating consequences of HIV dementia.
• Several studies have shown that early and aggressive treatment of HIV infection decreases the rate of dementia from greater than 50% to 10%.
• Multiple studies have shown that patients on HAART show partial reversals of neuropsychological deficits and significant improvement, which is sustained, whereas patients not on HAART steadily decline.
