Blood diseases in old age.
There is an increased incidence of chronic disease in old age, and blood disorder is not uncommon. Some diseases are more frequent in the latter half of life, while others -- such as the hereditary disorders -- are rare and occur only in a mild degree. Diagnosis of blood disease is more difficult in the elderly because symptoms of anaemia such as weakness, shortness of breath and mental disorder are often attributed to old age.
