Mood and anxiety disorders as early manifestations of medical illness: a systematic review

BACKGROUND

Affective disturbances involving alterations of mood, anxiety and irritability may be early symptoms of medical illnesses. The aim of this paper was to provide a systematic review of the literature with qualitative data synthesis.

METHODS

MEDLINE, PsycINFO, EMBASE, Cochrane, and ISI Web of Science were systematically searched from inception to February 2014. Search terms were 'prodrome/early symptom', combined using the Boolean 'AND' operator with 'anxiety/depression/mania/hypomania/irritability/irritable mood/hostility', combined with the Boolean 'AND' operator with 'medical illness/medical disorder'. PRISMA guidelines were followed.

RESULTS

A total of 21 studies met the inclusion criteria and were analyzed. Depression was found to be the most common affective prodrome of medical disorders and was consistently reported in Cushing's syndrome, hypothyroidism, hyperparathyroidism, pancreatic and lung cancer, myocardial infarction, Wilson's disease, and AIDS. Mania, anxiety and irritability were less frequent.

CONCLUSIONS

Physicians may not pursue medical workup of cases that appear to be psychiatric in nature. They should be alerted that disturbances in mood, anxiety and irritability may antedate the appearance of a medical disorder.

Fatigue and aging

Fatigue is the most common chronic symptom of cancer and the symptom most likely to disrupt the patient's activity and to cause disability.Fatigue affects older cancer patients to the same order of magnitude as younger ones and appears to be related to different factors such as anemia, depression, and reduced neuromuscular energy production. Interestingly, some studies have suggested that the duration of fatigue may be age-related. In the elderly, fatigue may cause functional dependence; functional dependence may lead to interruption of treatment, decline in quality of life and expensive home care. Available interventions include reduction of centrally acting drugs, management of anemia and metabolic abnormalities, and management of depression, treatment of sleep disorders, correction of endocrine abnormalities and realistic exercise programmes.
