Summary
Random forest models accurately identified declarative memory profiles in panic disorder (PD) patients using clinical data. Body mass index (BMI) emerged as a significant factor influencing memory in PD.
Area of Science:
- Neuroscience
- Psychiatry
- Machine Learning
Background:
- Panic disorder (PD) is associated with cognitive impairments, including declarative memory deficits.
- Understanding these deficits is crucial for developing targeted interventions.
Purpose of the Study:
- To create a classification framework using random forest (RF) modeling.
- To delineate the declarative memory profile in PD patients compared to healthy controls.
Main Methods:
- Developed RF models to classify declarative memory using Rey Auditory Verbal Learning Test (RAVLT) scores.
- Utilized clinical data from 299 PD patients in Rio de Janeiro.
- Included demographic and anthropometric data such as sex, age, and body mass index (BMI).
Main Results:
- RF models achieved high accuracy in predicting declarative memory profiles (AUC > 0.979).
- Models effectively used bias-free clinical data like sex, age, and BMI.
- Body mass index (BMI) was identified as a significant factor in declarative memory.
Conclusions:
- The developed framework accurately classifies declarative memory in PD patients.
- Clinical features, particularly BMI, are important correlates of declarative memory in PD.
- The framework offers a potential tool for future research on PD cognitive function.

Panic Disorder
115
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...

Generalized Anxiety Disorder

Generalized Anxiety Disorder (GAD) is a chronic condition characterized by excessive and uncontrollable worry that persists for at least six months, significantly interfering with daily functioning. Unlike situational anxiety, which arises in response to specific stressors, GAD often occurs without a clear cause. Individuals may experience disproportionate worry about work, health, or relationships. For instance, a person might continuously fear poor health despite normal medical evaluations or...
