Consultation-Liaison Psychiatry Practice Questions

Q: Which type of pain is primarily associated with psychological factors and lacks a clear physical cause?

Pain with no identifiable physical cause. ***Pain with no identifiable physical cause*** - This describes **psychogenic pain** (also termed **somatic symptom disorder** in modern classification), where psychological factors like stress, anxiety, or depression significantly contribute to the experience of pain without a clear **physical pathology**. - The pain is real to the individual, even if a physical origin cannot be found, highlighting the strong **mind-body connection**. - Common in **conversion disorder**, **somatization disorder**, and **persistent somatoform pain disorder** (ICD-10). *Pain caused by nerve damage* - This is **neuropathic pain**, a type of chronic pain resulting from damage to the **somatosensory nervous system**. - It has a clear physical cause, such as **diabetic neuropathy**, **post-herpetic neuralgia**, or a **herniated disc**. *Pain resulting from physical injury* - This is **nociceptive pain**, which arises from actual or threatened damage to **non-neural tissue** and is due to the activation of **nociceptors**. - Examples include sprains, fractures, burns, or post-surgical pain, all of which have a clear **physical etiology**. *Pain from internal organs* - This is **visceral pain**, which originates from internal organs and is often described as diffuse, deep, and poorly localized. - It has a clear anatomical source, such as **appendicitis**, **gallstones**, **myocardial infarction**, or **ureteral colic**.

Q: The most common postoperative psychiatric condition is:

Delirium. ***Delirium*** - **Delirium** is the most common postoperative psychiatric condition, characterized by an acute onset of **waxing and waning attention**, **disorganized thinking**, and altered level of consciousness. - It is often seen in elderly patients and those with pre-existing cognitive impairment, due to the stress of surgery, anesthesia, and medication effects. *Schizophrenia* - **Schizophrenia** is a chronic psychotic disorder with onset typically in late adolescence or early adulthood, characterized by hallucinations, delusions, and disorganized thinking. - It is not typically triggered by surgery but rather a long-term psychiatric illness with a different etiology. *Chronic brain syndrome* - **Chronic brain syndrome** is an outdated term typically used to describe **dementia** or other persistent cognitive impairments. - While patients with chronic cognitive impairment are at higher risk for postoperative delirium, chronic brain syndrome itself is not an acute postoperative psychiatric condition. *Depression* - **Depression** is a common mood disorder characterized by persistent sadness, loss of interest, and other symptoms. - While depression can occur postoperatively, especially in patients with prolonged recovery or poor outcomes, it is typically not the most common acute psychiatric condition immediately following surgery.

Q: Neuropsychiatric complications of HIV include all except which of the following?

Bipolar disorder. ***Bipolar disorder*** - While individuals with HIV may experience mood disorders, **bipolar disorder** is not considered a direct neuropsychiatric complication of the HIV virus itself. - The prevalence of bipolar disorder in HIV-positive individuals is similar to the general population, suggesting it's not causally linked to HIV neuropathogenesis. *HIV-associated dementia* - **HIV-associated dementia** (HAD) is a common and severe neuropsychiatric complication directly caused by chronic HIV infection in the central nervous system. - It manifests as progressive cognitive decline, motor dysfunction, and behavioral changes. *Depression* - **Depression** is a prevalent neuropsychiatric complication in HIV-positive individuals, often due to a combination of physiological effects of the virus, psychosocial stressors, and medication side effects. - It significantly impacts quality of life and adherence to antiretroviral therapy. *Psychosis* - **Psychosis**, including symptoms like hallucinations and delusions, can occur in HIV-infected individuals, particularly in advanced stages or when complicated by opportunistic infections or medication effects on the brain. - This can be a direct result of HIV's impact on neural pathways or a consequence of secondary CNS issues.

Q: What is the most common postoperative psychiatric complication?

Delirium. ***Delirium*** - **Delirium** is the most frequent postoperative psychiatric complication, especially in elderly patients and those undergoing major surgery. - It is an acute **neuropsychiatric syndrome** characterized by fluctuating attention, disorganized thinking, and altered level of consciousness. - Incidence ranges from **15-50% in elderly surgical patients** and **up to 80% in ICU settings**. *Depression* - Postoperative depression is common but typically emerges days to weeks after surgery, unlike the acute onset of **delirium**. - While it can significantly affect recovery, its incidence directly after surgery is lower than that of **delirium**. *Psychosis* - Postoperative psychosis is relatively rare and often linked to pre-existing psychiatric conditions, substance withdrawal, or severe medical complications. - It involves more severe thought disturbances and hallucinations than the more common **delirium**. *Anxiety* - Postoperative anxiety is common and can affect recovery, but it is typically **less severe** than delirium. - Unlike delirium, anxiety does not involve altered consciousness or acute cognitive impairment requiring immediate psychiatric intervention.
