Panic Disorder01:27

Panic Disorder

1.0K
Panic disorder is an anxiety disorder characterized by recurrent and sudden minutes-long episodes of intense fear, known as panic attacks. These attacks may feel like heart attacks and often happen without warning or a specific cause. They can include symptoms such as rapid heart rate, shortness of breath, chest pain, trembling, sweating, dizziness, and a sense of helplessness. During a panic attack, individuals may feel as though they are experiencing a heart attack or are in a...

Hormonal Regulation01:40

Hormonal Regulation

50.2K
Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.

Chronic Pancreatitis I: Introduction

860
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...

Acute Pancreatitis II: Clinical Manifestations and Management

1.0K
Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...

Intestinal Phase of Digestion01:29

Intestinal Phase of Digestion

12.1K
The intestinal phase of digestion is the third and final stage of the digestive process, occurring after the cephalic and gastric phases. It begins when chyme, a partially digested mixture of food and digestive enzymes, enters the small intestine from the stomach. This phase is crucial for nutrient absorption and involves complex hormonal and enzymatic interactions.
The arrival of the chyme in the small intestine distends the duodenum, which triggers the enterogastric reflex. This distension...

Summary

Cholecystokinin (CCK) plays a role in the neurobiology of panic disorder. Further research is needed to understand CCK-2 agonists

Area of Science:

  • Neurobiology
  • Pharmacology
  • Psychiatry

Background:

  • Panic disorder is a debilitating anxiety disorder with complex neurobiological underpinnings.
  • Cholecystokinin (CCK) is a neuropeptide implicated in various brain functions, including stress and anxiety responses.

Purpose of the Study:

  • To review existing evidence on the role of cholecystokinin (CCK) in the neurobiology of panic disorder.
  • To discuss the selectivity of CCK-2 agonists in anxiety disorders and potential aberrations in the CCK system.

Main Methods:

  • Review of animal and human pharmacological studies.
  • Analysis of the selectivity of CCK-2 agonists.
  • Examination of CCK system aberrations in anxiety disorders.

Main Results:

  • Pharmacological studies provide evidence for CCK's involvement in panic disorder.
  • Key issues identified include the specific action of CCK-2 agonists and alterations within the CCK system.

Conclusions:

  • The cholecystokinin system is a potential target for understanding and treating panic disorder.
  • Further investigation into CCK-2 agonist selectivity and CCK system dysregulation is warranted.
