Intrinsically Disordered Proteins02:18

Intrinsically Disordered Proteins

19.4K
Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

Other Disorders of Digestive System

The gastrointestinal tract is susceptible to various disorders. If the lower esophageal sphincter is damaged, stomach acid can flow back into the esophagus, causing irritation and inflammation of the lining. This condition is called gastroesophageal reflux disease (known as heartburn) and may cause chest pain and difficulty swallowing. In the stomach, prolonged use of nonsteroidal anti-inflammatory drugs like aspirin, chronic alcohol consumption, bacterial infections such as Helicobacter...

Disorders of Erythrocytes

2.2K
Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
On the other...

Disorders of Leukocytes

1.9K
Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...

Bone Disorders01:29

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Panic Disorder01:27

Panic Disorder

705
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...

Summary

Delusional disorder, a rare psychotic illness, often lacks systematic study. Aripiprazole showed promise in treating a patient unresponsive to risperidone, suggesting its potential efficacy.

Area of Science:

  • Psychiatry and Behavioral Sciences
  • Neuroscience
  • Pharmacology

Background:

  • Delusional disorder is a rare psychotic illness distinct from schizophrenia, characterized by persistent, non-bizarre delusions.
  • Limited systematic research exists for delusional disorder, with treatment guidelines primarily based on case reports and small series.
  • Antipsychotic medications are the standard treatment, but evidence comparing specific agents is scarce.

Observation:

  • A case of delusional disorder is presented where the patient did not respond to risperidone treatment.
  • The patient experienced significant improvement after switching to aripiprazole therapy.
  • This observation highlights potential differential responses to antipsychotic medications in delusional disorder.

Findings:

  • Aripiprazole demonstrated marked efficacy in a patient with delusional disorder refractory to risperidone.
  • The patient's delusional symptoms resolved or significantly diminished with aripiprazole treatment.
  • This suggests aripiprazole may be a valuable therapeutic option for delusional disorder.

Implications:

  • Aripiprazole's efficacy warrants further investigation as a potential treatment for delusional disorder.
  • The drug's combined dopaminergic and serotonergic activity may underlie its effectiveness in this condition.
  • Further clinical trials are needed to establish aripiprazole's role in managing delusional disorder.
