4. Sleep disturbances: Depression can also cause changes in sleep patterns, leading to insomnia or excessive sleeping.
5. Fatigue or loss of energy: People with depression may feel constantly tired, lacking energy and motivation to perform even basic tasks.
6. Difficulty concentrating or making decisions: Depression can cause difficulties in concentration, memory, and decision-making.
