Neurovegetative symptoms in chronic pain and depression
Journal of Affective Disorders
|November 1, 1985
Summary
Chronic pain patients frequently experience depressive illness, with major depressives showing distinct neurovegetative symptoms. Atypical depression may be linked to chronic pain, presenting reversed vegetative symptoms.
Area of Science:
- Psychiatry
- Pain Medicine
- Neuroscience
Background:
- Depressive illness is common in chronic pain patients, yet its specific presentation requires further elucidation.
- Neurovegetative symptoms are key diagnostic criteria for depression, but their manifestation in chronic pain populations is not fully understood.
- Previous research has not extensively explored the relationship between atypical depression and chronic pain.
Purpose of the Study:
- To investigate the pattern and frequency of neurovegetative symptoms in patients with chronic pain.
- To differentiate depressive subtypes within a chronic pain cohort.
- To explore potential links between atypical depression and chronic pain.
Main Methods:
- Study involved 57 patients diagnosed with chronic pain.
- Patients were categorized into major depressives, minor/intermittent depressives, and non-depressed groups.
- A control group of major depressives without pain was included for comparison.
Main Results:
- 79% of chronic pain patients had diagnosable depressive illness; endogenous depression was rare (5%).
- Major depressives with chronic pain exhibited more severe early waking, weight loss, anorexia, diminished libido, and initial insomnia.
- Over one-third of minor/intermittent depressed chronic pain patients showed atypical symptoms like hyperphagia and weight gain.
Conclusions:
- Major depressives with chronic pain share a neurovegetative symptom profile similar to major depressives without pain.
- Diurnal mood variation was not characteristic of major depression in chronic pain patients.
- A significant association between atypical depression and chronic pain is suggested by the prevalence of reversed vegetative symptoms.

01:44Nociception
Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain. Thus, pain helps the...
01:25Analgesia and Pain Management
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...
01:18Depression: Overview
Depression is a prevalent mental illness marked by persistent sadness and lack of interest in previously enjoyable activities. It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts. From a neurobiological perspective, depression is believed to be triggered by abnormalities in the brain's prefrontal cortex,...
01:30Stress and Mental Health
Chronic stress profoundly affects mental health, significantly influencing mood, behavior, and overall quality of life. Research closely links chronic stress with mental health conditions such as depression, anxiety, and substance use disorders. Ongoing exposure to stress can lead to physiological and psychological changes, initiating a cycle of emotional distress and maladaptive coping mechanisms.

01:27Depressive Disorders: MDD and Dysthymia
Depressive disorders are a group of mental health conditions characterized by pervasive feelings of sadness, diminished pleasure in life, and a significant impact on daily functioning. These conditions are most prevalent in individuals during their 30s and affect women at twice the rate of men. Contrary to popular belief, younger individuals are generally more susceptible to these disorders than older adults. Two key types of depressive disorders include Major Depressive Disorder (MDD) and...
01:30Negative and Cognitive Symptoms of Schizophrenia
Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...
