Leo is likely suffering from bipolar disorder, also known as manic-depression (see the link below for more information). People with this mental illness suffer from periods of depression intermixed with manic periods during which they often experience changes in their sleep patterns and energy levels. Leo is clearly suffering from mild to moderate depression, as he has lost interest in activities he used to enjoy, though he does not have other serious symptoms of depression such as gaining or losing weight or being suicidal. He experiences periods of intense activity in which he stays up all night and then he speaks very quickly, which can be signs of mania. He also occasionally spends a lot of money, which is also a sign of mania. However, none of these symptoms are severe enough to interfere with his work. Therefore, he likely has a mild to moderate case of bipolar disorder.
