The right hemisphere brings anxious, disturbed depression while the left brings indifferent or apathetic depression
There is also evidence that the types of depression experienced in right posterior hypoactivity are different from those experienced in left frontal hypoactivity, in ways which are in keeping with the views of the worlds that the two brain hemispheres bring into being. Thus depression resulting from damage to the right hemisphere has more of indifference or apathy – a global, vague lifelessness – in contrast to the anxious, disturbed depression, accompanied by biological features, resulting from lesions to the left hemisphere. The sort of anxiety that accompanies depressed mood, and could be induced by reading a sad narrative, is known as anxious arousal, and shows greater lateralisation to the right hemisphere. By contrast anxious apprehension, based as it is on a fear of uncertainty and lack of control—preoccupations of the left hemisphere—is accompanied by preferential left hemisphere activation.
