Summary
Understanding pain is crucial for chronic pain research. The International Association for the Study of Pain (IASP) defines pain and classifies chronic pain types, highlighting three key mechanisms: nociceptive, neuropathic, and nociplastic pain.
Area of Science:
- Pain research
- Neuroscience
- Medical classification
Context:
- The International Association for the Study of Pain (IASP) provides a definition of pain.
- Pain is recognized as a complex, personal experience influenced by biological, psychological, and social factors.
- Chronic pain can negatively impact physical, social, and psychological health.
Purpose:
- To elucidate the fundamental understanding of pain.
- To introduce the IASP's classification system for chronic pain, including chronic secondary and primary pain.
- To outline the three primary pain mechanisms relevant to treatment: nociceptive, neuropathic, and nociplastic pain.
Summary:
- The IASP defines pain as an unpleasant sensory and emotional experience linked to tissue damage.
- IASP's ICD-11 classification distinguishes between chronic secondary pain (clear organic factors) and chronic primary pain (difficult to explain organically).
- Effective pain treatment requires consideration of nociceptive, neuropathic, and nociplastic pain mechanisms, the latter involving nervous system sensitization.
Impact:
- Enhances understanding of chronic pain pathomechanisms.
- Provides a framework for classifying and diagnosing chronic pain conditions.
- Informs clinical approaches to pain management by considering diverse pain mechanisms.

01:25Analgesia and Pain Management
701
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...

Pain serves as a critical warning signal that alerts the body to potential or actual harm. When mechanical pressure on the skin is intense, such as from a sharp pinch, the sensation transitions from touch to pain. Similarly, extreme temperatures, like a hot pot handle, convert the sensation of heat into pain. Pain can also result from overstimulation of other senses, such as blinding light, loud noise, or the intense heat from habañero peppers. This ability to sense pain is essential for...

01:44Nociception
28.2K
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.

01:24Chronic Pancreatitis I: Introduction
127
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...

01:17Chronic Bowel Disorders: Introduction
512
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...
