HIV and Cognitive Impairment
• Cognitive complaints are common in HIV
– Acute delirium secondary to legion of metabolic and
infectious complications
– HIV-associated neurocognitive disorders - directly
related to the presence of the virus in the CNS
(HAND)
– Other chronic cognitive impairments not directly
related to HIV (alcohol and/or other drugs, Hep C,
vascular)
– Cognitive symptoms associated psychiatric illness

Consensus Working Group, Neurology 2007
HIV related risk factor for
Neurocognitive Disorders
• BEFORE HAART
• Cognitive impairment associated with HIV
recognised from early in epidemic
– Usually with advanced disease
– Often a prelude to death
– Both dementia and milder forms of cognitive
impairment described
www.aids2014.org
HIV related risk factor for
Neurocognitive Disorders
• AFTER HAART - people living longer
– Cognitive symptoms were seen to persist but often
milder
– Length of HIV infection and lowest CD4 Count
– The brain is a “sanctuary site”
– Aging peoples with co-morbidities
www.aids2014.org
Other factors in cognitive
impairment
• Smoking
• Alcohol & drug use
• Other viral infections which contribute to
brain injury eg HCV
• Other brain infections such as meningitis
• Head injury
www.aids2014.org
Other factors in cognitive
impairment
•
•
•
•
•
Diabetes
High Blood Pressure
Older age >45 years
Obstructive Sleep Apnoea
High cholesterol
www.aids2014.org
HIV Neurocognitive Disorders
• Up to 60% of people with HIV will have a
neuro-cognitive abnormality
(asymptomatic or only mild impairment in
the majority)
www.aids2014.org
Mild Neurocognitive Disorder
(MND)
• An acquired impairment of cognitive
functioning that involves at least two ability
domains ( memory, concentration, language, motor,
social, executive function)
• This impairment produces interference
with daily functioning
www.aids2014.org
Other issues
• Vast majority have mild or no symptoms
• People may not volunteer symptoms from
lack of awareness or insight
• Clinical Carers may not have relevant
training for diagnosis and management of
HAND
• Clinical Carers may be focused on other
issues in busy clinic settings
www.aids2014.org
MND may be missed
• Changes are slow and subtle
• Symptoms may go unreported, as people
and family attribute changes to:
• Understandable stress responses to life events or to
illness itself
• Normal aging
• Depression
www.aids2014.org
Depression in HIV
• In HIV symptoms of depression overlap
–
–
–
–
with understandable unhappiness
with symptoms of cognitive impairment
with symptoms of physical illness eg fatigue
Diurnal variation of mood suggests depression
varidddddation of mood suggests depression
• Cornerstone of depression is not sadness,
but the symptoms of anhedonia
www.aids2014.org
ANHEDONIA
• Is the inability to experience pleasure from
activities usually found enjoyable, e.g.
• Hobbies
• Music
• Sexual activities
• Social interactions
• Exercise
www.aids2014.org
Impact of depression in HIV
infection
Depression in HIV people is under diagnosed
High prevalence
Depression in HIV is undertreated
Health costs
www.aids2014.org
Poorer outcome of
HIV disease
Quality of life
MND - Detection
• Clinical carers should be alert for evolving
cognitive impairment and screen for its
presence even in people with undetectable
viral load
• Both people and their significant others
should be questioned
www.aids2014.org
If Cognitive Impairment is detected
• Exclude depression
• Exclude other potentially reversible causes
of cognitive impairment
– acute medical illness
– alcohol and other recreational drug use,
cerebro-vascular disease, neuroimaging for
OIs
• HAND is a diagnosis of exclusion
www.aids2014.org
Prognosis for Mild Neurocognitive
Disorder
•
A significant proportion will get better with
treatment
•
In a year, with treatment, 21% will improve
from milder impairment to unimpaired
•
In the same time, without treatment, 23% will
move from unimpaired to MND
•
Antiretroviral therapy that works better in the
brain leads to better outcomes

Mild Neurocognitive Disorder
Summary
•Cognitive impairment continues to be an
important problem for people living with HIV
•Both dementia and MND should be screened for
•They can be recognized clinically and confirmed
with neuropsychological testing
www.aids2014.org
Mild Neurocognitive Disorder
Summary
Cognitive impairment in HIV can be
managed
• Antiretroviral therapy that better
distributes into the CNS leads to better
outcomes
• Co-morbid risk factors can be minimised
• Physical exercise and mental
stimulation- Use it or lose it !

Fact Sheet Number 558
DEPRESSION AND HIV
HIV medications. Fact Sheet 729 has more about St. John’s W ort. Be sure
to tell your health care provider if you are taking St. John’s Wort.
WHAT IS DEPRESSION?
•
Problems sleeping: waking very early, or excessive sleeping
Depression is a mood disorder. It is more than sadness or grief.
Depression is sadness or grief that is more intense and lasts longer than
it should. It has various causes:
•
events in your daily life
•
chemical changes in the brain
•
a side effect of medications
•
several physical disorders
•
•
•
Feeling guilty, worthless, or hopeless
Decreased appetite or weight loss
Overeating
Valerian or Melatonin may help improve your sleep. Supplements of
vitamins B6 or B12 can help if you have low levels of these vitamins.
WHAT CAUSES DEPRESSION?
Antidepressants
Some people with depression respond best to medication. Antidepressants
can interact with ARVs. They must be used under the supervision of a
health care provider who is familiar with your HIV treatment. Protease
inhibitors have many interactions with antidepressants.
About 5% to 10% of the general population gets
depressed.
However,
rates
of depression in people with HIV are as high as 60%. Women
with HIV are twice as likely as men to be depressed.
Being depressed is not a sign of weakness. It doesn’t mean you’re going
crazy. You cannot “just get over it.” Don’t expect to be depressed because
you are dealing with HIV. And don’t think that you have to be depressed
because you have HIV.
Some medications used to treat HIV can cause or worsen depression,
especially efavirenz (Sustiva). Diseases such as anemia or diabetes
can cause symptoms that look like depression. So can drug use, or low
levels of testosterone, vitamin B6, or vitamin B12.
People who are infected with both HIV and hepatitis (see fact sheet 506)
are more likely to be depressed, especially if they are being treated with
interferon.
The tricyclics have more side effects than the SSRIs. They can also cause
sedation, constipation, and erratic heart beat.
Other risk factors include:
•
Being female
Some health care providers also
used to treat attention deficit disorder.
IS DEPRESSION IMPORTANT?
•
Depression can lead people to miss doses of their medication. It can
increase high-risk behaviors that transmit HIV infection to others.
Depression might cause some latent viral infections to become active.
Overall, depression can make HIV disease progress faster. It also interferes
with your ability to enjoy life. A study in 2012 showed that patients with
depression, especially women, were more likely to stop receiving care and
to not achieve undetectable viral load.
•
•
•
substance abuse
A
Not having enough social support
Not telling others you are HIV-positive
Treatment failure (HIV or other)
(DHEA)
THE
SIGNS
Symptoms of depression vary from person to person. Most health care
providers
Lifestyle changes can improve depression for some people. These include:
suspect depression if patients report feeling blue
or
having
very
little
interest in daily activities. If these feelings go on for two weeks or
longer, and the patient also has
some of the following symptoms, they are probably depressed:
•
•
•
Fatigue or feeling slow and sluggish
Problems concentrating
Low sex drive
study
showed
that
treatment
with dehydroepiandrosterone
can reduce depression in some HIV patients.
Depression is a very common condition for people with HIV. Untreated
Depression can be treated with lifestyle changes, alternative therapies,
and/or with medications.
Many
medications
and therapies for
depression can interfere with your HIV treatment. Your health care
provider can help you select the therapy or combination of therapies most
appropriate for you. Do not try to self-medicate with alcohol or
recreational drugs, as these can increase
depression and create
additional problems.

THE BOTTOM LINE
TREATMENT FOR DEPRESSION
ARE
use psychostimulants, the drugs
Having a personal or family history of mental illness, alcohol and
Depression often gets overlooked. Also, many HIV specialists have not
been trained to recognize depression. Depression can also be mistaken
for signs of advancing HIV.
WHAT
The most common antidepressants used are
Selective
Serotonin
Reuptake Inhibitors, called SSRIs. They can cause loss of sexual desire
and function, lack of appetite, headache, insomnia, fatigue, upset stomach,
diarrhea, and restlessness or anxiety.

Regular exercise
Increased exposure to sunlight
Stress management
Counseling
Improved sleep habits
depression can cause you to miss medication doses and lower your quality
of life.
Depression is a “whole body” issue that can interfere with your physical
health, thinking, feeling, and behavior.
The earlier you contact your health care provider, the sooner you can
both plan an appropriate strategy for dealing with this very real health
issue.
