Symptoms associated with depression

Not all persons with depressive states present the same symptoms, since the frequency and duration of symptoms varies depending on the type of depression that the person is going through.


  • Feelings of sadness, loneliness or emptiness that last most of the day for several days
  • Loss of interest or pleasure in activities that used to be nice
  • Fatigue and chronic low energy
  • Difficulty thinking clearly, concentration, make decisions or remember
  • Feelings of being useless, guilt and powerlessness
  • Feelings of irritability, frustration or anger that are disproportionate to the circumstances
  • Restlessness and agitation
  • Sleep disorders, including sleeping too much and too little (insomnia)
  • The change of appetite, often leads to weight loss, although some people may have increased appetite and weight gain
  • Recurrent thoughts of death or suicide, as well as suicide attempts or plans
  • Aches and persistent pains, such as headaches or stomach upset


In some cases depression co-exists with mental disorders such as anxiety, posttraumatic stress, obsessive compulsive disorder, panic or phobia. Likewise, depression can be generated as a result of abuse, alcohol dependence or other substances, or as a result of medical conditions such as heart disease, cancer, diabetes, Alzheimer's or HIV/AIDS, among others.
