  • Biological treatments for DB
    • Drugs
      • Work on neurochemical transmitters in the brain to treat the symptoms
        • For example, depression is linked to low norepinephrine and serotonin
          • Anti-depressants prolong the effects of these neurotransmitters by blocking reuptake into the neuron that released them
            • Might also increase the amount that is accumulated in that neuron
      • Effectiveness is impacted by weight, gender, age etc
    • Electroconlusive therapy
      • Used on drug resistant depressive patients
        • Brain stimulation occurs through electrodes placed on the head
          • This is followed by a series of electrical pulses
      • Two main types
        • Unilateral - one, dominant hemisphere is stimulated
        • Bilateral - both hemispheres are stimulated
      • Believed to work due to changes in neurotransmitter levels
        • Including sensitivity to serotonin and the hypothalamus
    • Psychosurgery
      • Used for  OCD and depression
        • 2001 - cingulotomies effective on 56% of OCD patients & 65% of those with a major effective disorder
      • Neurosurgeons use MRIs to locate exact points within the brain and sever connections
        • For example, the thalamus of OCD sufferers is more active than usual
          • Cingulotomy is used to burn away tissue by heating up the tip of an electrode
            • Beams are then focused on a target site
    • Karp + Frank
      • Aim: compare drug and non drug treatment for depression
        • Method: review article of single + combined treatments (drug and psychotherapeutic) of depression, focusing on women
          • Procedure: depression analysed by questionnaires, and generally patients were tested prior to and post treatment
            • Findings: adding psychological treatments to drug therapies did not increase the effectiveness of the drugs
              • Findings 2: less attrition when combined treatments was used
                • Conclusion: evidence did not show any better outcomes for patients on combined therapy as opposed to just drug therapy
