Vegetative symptoms

Not to be confused with Vegetative state.

Vegetative symptoms are disturbances of a person's functions necessary to maintain life (vegetative functions). These disturbances are most commonly seen in mood disorders, and are part of the diagnostic criteria for depression, but also appear in other conditions.^[1]

Vegetative symptoms in a patient with typical depression include:^[2]

• Weight loss and loss of appetite
• Insomnia
• Fatigue and low energy
• Inattention

Reversed vegetative symptoms

Reversed vegetative symptoms include only oversleeping (hypersomnia) and overeating (hyperphagia), as compared to insomnia and loss of appetite. These features are characteristic of atypical depression.

However, there have been studies^[3] claiming that these symptoms alone are sufficient to diagnose the condition of atypical depression.
