Bipolar disorder/ depression

Bipolar Disorder

A mood disorder characterized by extreme and persistent mood swings affecting more than 1-2% of the population worldwide.

Mania

Episodes characterized by euphoria, irritability, increased activity, and other symptoms like talkativeness, grandiosity, and impulsivity.

Bipolar 1

Less common type characterized by periods of mania and depression that may or may not reach the threshold for major depression.

Bipolar 2

More common type characterized by periods of hypomania and major depression.

Rapid Cycling

Repeated switching between depression and mania without a 'normal' stage in between, affecting some individuals with bipolar disorder.

Mixed State

When an individual experiences symptoms of both depression and mania simultaneously, leading to difficulties in coping, unpredictability, and increased risk of acting on suicidal thoughts.

Biological Explanations

Include genetic and epigenetic changes, structural and functional brain changes, immune system alterations, and neuronal plasticity impairments.

Neuroanatomical Differences

In individuals with bipolar disorder, such as increased activation in the amygdala and thalamus, and abnormalities in emotional control networks in the brain.

Biological Treatments

Include mood stabilizers like lithium, antipsychotics, electroconvulsive therapy, and transcranial magnetic stimulation for managing bipolar disorder symptoms.

Conative Explanations

Beck's theory of mania as the mirror image of depression, involving positive cognitive distortions like high self-esteem and hyper-positive conative distortions.

Treatment

Cognitive-behavioral therapy (CBT) and medication have positive impacts on clinical symptoms, treatment adherence, and quality of life in individuals with bipolar disorder.
