Seasonal Affective Disorder (SAD) Guide

What is Seasonal Affective Disorder?

Seasonal Affective Disorder (SAD) is a type of depression that occurs at a specific time of the year, most commonly during fall and winter when daylight hours are shorter. It affects mood, energy levels, and daily functioning, with symptoms often easing as seasons change and daylight increases.

Classify Seasonal Affective Disorder

Classification:
SAD is classified as a Mood Disorder and a subtype of Major Depressive Disorder with a seasonal pattern. It’s related to the body’s circadian rhythm and changes in light exposure, affecting brain chemistry and mood regulation.

Types of Seasonal Affective Disorder Issues

Winter-Onset SAD: Most common type, with symptoms appearing in late fall or early winter and improving in spring or summer.
Summer-Onset SAD: A rarer type, with symptoms starting in late spring or early summer and improving during fall or winter.

Signs and Symptoms

Winter-Onset SAD Symptoms:

Fatigue and low energy.
Oversleeping and difficulty waking up.
Increased appetite and weight gain, especially craving carbohydrates.
Feelings of sadness, hopelessness, or worthlessness.
Difficulty concentrating.

Summer-Onset SAD Symptoms:

Insomnia or sleep disturbances.
Loss of appetite and weight loss.
Anxiety or irritability.
Restlessness or agitation.

Seasonal Affective Disorder Causes

Reduced Sunlight: Decreased daylight can disrupt circadian rhythms and lower serotonin levels.
Melatonin Imbalance: Changes in light exposure affect melatonin production, impacting sleep and mood.
