Therapies Flashcards
What are the aims of psychosurgery?
Psychosurgery aims to treat mental illness as Physical illnesses are treated using surgery to help improve mental illness.
What are the four main components of psychosurgery?
Two traditional
-trans orbital, lobotomy
-prefrontal leucotomy
Two modern
-bialateral cingulotomy
-deep brain simulation
What is a prefrontal leucotomy?
-two holes would be drilled in each side of the skull, after this a Leucotome is inserted through the holes and moved side to side, to cut off the connections between the frontal lobe and the rest of the brain.
What is a transorbital lobotomy?
A patient is knocked unconscious using electro convulsive therapy, an ice pick is then inserted under the eye lid and into the frontal lobe of the brain, the ice pick is then moved around to destroy connections between the prefrontal area and other brain regions.
What is a bialateral cingulotomy?
- an incision is made in the nerves of the brain using mri scans to show which nerve endings are being severed. No area of the brain is damaged or removed, only the nerve endings are cut off.
What is deep brain stimulation?
Two small holes are drilled in to the skull and them electrodes are implanted on the targeted brain area, the electrodes are connected to an implanted neurostimulator, in the chest area of the patient, this alters the levels of stimulation in the brain.
What is a strength of psychosurgery regarding effectiveness?
-supporting evidence: showed that cingulotomys where effective on 56% of patients with ocd
-however shows this wasn’t effective on 44% of people with ocd
What is one weakness of psychosurgery regarding effectiveness?
Sever side effects-
The fatality rate of early psychosurgery is 6%, there is also a chance of: memory loss, lack of concentration, and being left in a vegetative state.
What is a weakness of psychosurgery in terms of ethics
-informed consent
patience with conditions, such as schizophrenia may have a compromised mental state so may not be able to give consent.
-harm
The side-effects received after psychosurgery cause physical harm to the patient, for example, memory, loss, seizures, and being left in a vegetative state.
What are the aims of systematic desensitisation?
Systematic desensitisation is based on the principles of classical conditioning. This means that fears are conditioned into us, systematic desensitisation aims to count condition this, by associating fearful stimuli with something positive.
What are the main components of systematic desensitisation?
-in vitro/in vivo
– Anxiety hierarchy
– Relaxation technique
– Reciprocal inhibition
– Gradual exposure
What is in vitro exposure?
-sd
-why are you don’t actually face the feared stimuli however, you can use VR or imagine the stimuli
What is in vivo exposure?
-sd
-in vivo exposure is where you actually face the feared stimuli in real life
What is an anxiety hierarchy?
-SD
-an anxiety hierarchy is formed by the client and therapist working together to to rank the least fearful stimuli to the most fearful stimuli
Eg. A picture of a spider, maybe at the bottom and holding a spider, maybe at the top of the hierarchy.
What is an example of some relaxation techniques?
-SD
The client is taught techniques such as mindful breathing so that they can calm themselves down when facing feared stimuli
What is reciprocal inhibitaion?
-The client gradually works their way through the hierarchy, starting with the least fearful stimuli than when the client starts to have anxiety, they will use their relaxing techniques so they may start to visualise a stressful situation while remaining relaxed
What is gradual exposure?
The client moves through the anxiety hierarchy at their own pace, once they are calm with the phobic stimulus in front of them they will move up in the hierarchy
What is a strength of SD in terms of ethics
-systematic desensitisation is ethical compared to flooding as the patient is in control and they move through the hierarchy at their own pace.
What is a strength of systematic desensitisation in terms of effectiveness?
Lang and lazovik
-used Sd with students who had a snake phobia
-Over 11 sessions they worked through a hierarchy
-Sd was found to be effective for most and improvement was still evident six months later
