Biological explanation of unipolar depression

biological explanation of unipolar depression The biological causal factors in unipolar mood disorders are those which affect the levels of hormones such as cortisol and melatonin, or neurotransmitters such as serotonin, endorphins, gamma-aminobutyric acid and norepinephrine, all of which can alter mood and may be potential causes of depression.

Biology of depression - neurotransmitters although brain chemicals are certainly part of the cause, this explanation is too simple even just considering the biological dimension of depression, the brain has multiple layers of issues that are involved neurochemistry. The biological causal factors in unipolar mood disorders are those which directly affect the levels of certain chemicals in the body, specifically neurotransmitters which affect mood, and hormones which regulate the levels of those neurotransmitters, among other things.

The unit 2 exam expects you to know about one non-biological explanation of a disorder other than schizophrenia in this case, unipolar depression you are also expected to understand a psychological treatment for depression which is linked to these explanations. There is some evidence to suggest that depression may be due to heredity factors most research into this area looks at first degree biological relatives - having a first-degree relatives with depression appears to be risk factor for depression - family studies select people who already have. One biological explanation for unipolar depression is the monoamine hypothesis the monoamines are a group of neurotransmitters which include serotonin, noradrenaline and dopamine you will recognise the latter, dopamine, from the biological offering of an explanation for schizophrenia the monoamines are believed to regulate mood.

Major depressive disorder (mdd), also known simply as depression, is a mental disorder characterized by at least two weeks of low mood that is present across most situations it is often accompanied by low self-esteem, loss of interest in normally enjoyable activities, low energy, and pain without a clear cause. Unipolar mood disorders, by far the most common of which is unipolar depression, can happen to anybody they are usually triggered by a complex mixture of biological, social and environmental factors the biological causal factors in unipolar mood disorders are those which directly affect the levels of certain chemicals in the body, specifically neurotransmitters which affect mood, and.

Biological explanation of depression biological explanations of dysfunctional behaviour centres around physiology, and refers to aspects of biology such as genetics and brain functioning the biological explanation of depression specifically refers to two factors: neurotransmitter dysfunction and inherited genes. A 8-mark “evaluate” question awards 4 marks for describing biological explanations of unipolar depression (ao1) and 4 marks for evaluating them with reference to treatment (ao2) you need a conclusion to get a mark in the top band (7-8 marks) description unipolar depression has a biological explanation because it runs in families. Biological explanation of depression the results showed that there was an eight fold increase in unipolar depression among the biological parents of the adults in other words, adoptive parents were eight times less likely to have depression,.

You may have heard that depression is the result of a simple imbalance of brain chemicals although brain chemicals are certainly part of the cause, this explanation is too simple even just considering the biological dimension of depression, the brain has multiple layers of issues that are involved. Gershon (1990) - carried out a review of 10 family studies and found that the rates of unipolar depression in first degree relatives ranges between 7 and 30%, this range being higher than the incidence in the general population - this study suggests that there is a genetic link for depression as the % found is higher than that of the general population. One biological explanation for unipolar depression is the monoamine hypothesis the monoamines are a group of neurotransmitters which include serotonin, noradrenaline and dopamine you will recognise the latter, dopamine, from the biological offering of an explanation for schizophrenia.

Unipolar depression has a biological explanation because it runs in families gershon reviewed family studies and found people were 2-3 times more likely to get depression if a close family member suffered from it. Biological explanations of unipolar depression (22 marks) genetic influences (from psychology in focus): medical mode sees psychological problems as illnesses with physical causes genes are often singled out as 1 of the causes of depression. Current research suggests that a decrease in the production of serotonin by these neurons can cause depression in some people, and more specifically, a mood state that can cause some people to feel suicidal in the 1960s, the catecholamine hypothesis was a popular explanation for why people developed depression.
