- 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
- Anti-depressants prolong the effects of these neurotransmitters by blocking reuptake into the neuron that released them
- For example, depression is linked to low norepinephrine and serotonin
- Effectiveness is impacted by weight, gender, age etc
- Work on neurochemical transmitters in the brain to treat the symptoms
- 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
- Brain stimulation occurs through electrodes placed on the head
- 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
- Used on drug resistant depressive patients
- 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
- Cingulotomy is used to burn away tissue by heating up the tip of an electrode
- For example, the thalamus of OCD sufferers is more active than usual
- Used for OCD and depression
- 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
- Findings 2: less attrition when combined treatments was used
- Findings: adding psychological treatments to drug therapies did not increase the effectiveness of the drugs
- Procedure: depression analysed by questionnaires, and generally patients were tested prior to and post treatment
