At its root, anhedonia is the inability to experience pleasure, but in recent years, the fields of medicine and psychology have expanded this definition. The characteristics of this condition include reduced motivation, a lack of desire for consumable items, and a loss of anticipation for experiences or activities. Some personality disorders include a component of anhedonia. There are two types of anhedonia: physical and social.
Physical anhedonia is a loss of interest and enjoyment related to physical sensations. This condition frequently leads to weight loss and malnutrition because the individual perceives food as bland and tasteless. This type of anhedonia also involves a lack of desire or tolerance for touch from other people. Hugs no longer feel like a sign of affection and sex can become a source of dread instead of joy and intimacy.
