When is a person said to be depressed, medically speaking?

It is when an individual feels low in mood or is often irritable. In layman’s terms, it is an affective disorder; which means it affects the emotions of the individual.

To make a diagnosis of depression, one needs to establish low mood, laughing all day or most times of the day for at least two weeks.

Is depression different from or similar to grief?

It is different, though their symptoms may look alike. Grief is in response to a loss of a loved one, a job or anything else that one holds dear. Grief is in response to something one was attached to but has lost. The response depends on how close one was to the person or object lost. It is expected that someone who loses something will grieve over it for some time and within that period, the severity of those symptoms is meant to wane. Within three or six months, it is expected that a person should be largely out of grief. If not, it is called pathological grief.

What are causes of depression?

Some of the causes include the personality of the individual. Some people have a dependent personality, which makes their chances of having depression higher. Another is the predisposition around the time of birth; for instance, the pregnancy, delivery and early childhood.

Does depression exist in different forms?

Depression is depression but we talk about unipolar depression in which each time an individual falls ill, they come down with depression. Depression usually has a time limit, so with or without treatment, some people get well. There is bipolar depression in which a person may occasionally be depressed and at other times, may be excited, what we call hypomania or manic illness. There is also a situation where there is a mixture of manic and depressive symptoms. When depression occurs in women after delivery, it is called postpartum depression.

What are the general symptoms of depression?

The primary symptoms include a change in mood which must be there almost all day or most of the day for at least two weeks. The individual feels tired easily, what we call easy fatigability. There is a loss of interest in things that ordinarily give the individual pleasure. For instance, someone who is depressed will not be interested in chatting, reading, exercising, doing sports, and hanging out. Those are the core symptoms of depression. Other things could be a change in sleep pattern; some have insomnia and find it difficult to sleep. The commonest is that people with depression can sleep for a while, wake up earlier than usual, two hours before the normal time, but are not able to go back to sleep. However, people may sleep more than usual.

Some people say they tend to eat more when the feel bad. Is this a sign of depression?

Another symptom is a change in appetite. More often an individual with this mood disorder may not be interested in eating, so they lose weight, or they could eat more than usual and then add weight. That means people tend to soak their depression in eating. When they find anything to eat, they eat just to keep their mouth moving. Also, depression causes some people to feel guilty, rejected, easily accept wrongdoing, and tend to apologise too often. Other symptoms are the feeling of hopelessness, worthlessness, and negative thoughts about the past, present, and future. If the condition is complicated, the individual tends to have a delusion of persecution, feeling that people are against or want to kill them. People could also hallucinate; they see things others around are not able to see, hear voices that others are not able to hear, and perceive bad odours emanating from their bodies that others are not able to perceive. When the individual sits down and someone nearby stands up and leaves, the depressed individual thinks the person left because of the bad odour.

Can a person with this mood disorder have suicidal thoughts?

Of course, suicidal thoughts may also come in, with the individual questioning their existence and thinking they are better off dead. Suicidal behavior comes in, from the ideation to the planning and possibly the full act of killing themselves.

Also, people believe and it has been documented that Africans tend to somatise, meaning that they convert their emotional issues into bodily symptoms. An average Caucasian may walk up to you weeping but an African may not weep even when they feel low in mood, based on their ethnic or religious backgrounds. So, they tend to suppress such feelings that eventually manifest in physical symptoms like body pains that cannot be attributed to any organ of the body as a peculiar way of presenting pain. So, in some people, depression may present as a peppery sensation in the body or heaviness of the head. Some feel a crawling sensation.

Can transferred aggression be attributed to depression?

It could be, because people who are depressed and cannot find expression for what they are going through tend to be irritable. They get unnecessarily angry. I refer to them as a time bomb.

Do the symptoms you have mentioned apply to males, females, teens and children?

Women are more likely to have some of the symptoms. Children don’t present with the classical weepy spells or begging for forgiveness. What they may do is to refuse to go to school because they are not able to concentrate, so their performance tends to fall.

What is the prevalence rate in Nigeria?

Generally, we believe that prevalence will range from five to 10 per cent but people have recorded higher figures, particularly in hospital prevalence studies. But for community studies, we talk about 10 per cent of the population.

Some people may consider 10 per cent as seemingly low, considering how hard the times are now for many Nigerians in the country. Don’t you think community prevalence could be higher?

Seemingly low? For a population of 220 million, 10 per cent is about 22 million. It is not low, looking at statistics but I can tell you that with the challenges we are facing in the country, that figure was probably obtained in 2001 or 2004. If you look at it in the present setting, it probably may be higher because of the economic situation, banditry and others. The happiness that people see is just on the surface. Every Nigerian has had symptoms of depression. We may not have been diagnosed but people have felt unhappy and unhappiness does not really translate to depression.
