evaluating physcosurgery Flashcards
how effective was early pyscosurgery?
it was inappropriate and ineffective, lobotomys had a death rate of up to 6% and had severe physical side effects like seizures and lack of emotional responsiveness.
how effective is modern pyscosurgery? such as cinugolotmy and capsulotomy in OCD patients and who reported this?
Cosgrove and rauch (2001) reported cingulotomys were effective in 56% of OCD patients and capsulotomys effective in 67% of OCD patients.
in patients with major effective disorders how effective were cingulotomys and capsulotomys?
65% with cingulotomys and 55% with capsulotmys
why could effectriveness in modern physcosurgery such as cingulotomys and capsulotomys be doubted?
Because the number of patients studied was very small- only 25 patients per year.
how affective has DBS been found to be? what’s an example of this effectiveness?
very effective in patients suffering with severe depression e.g. Mayberg found that 4 in 6 patients suffering with depression found striking improvements following treatment when being stimulated in a small area in the frontal cortex.
WHAT IS THE APPROPRIATNESS OF PYSCOSURGERY?
LIMITED IN ITS USE, ONLY USED TO TREAT CASES WITH SEVERE CASES. not use to treat schizophrenia, szaz (1987) criticised pyscosurgery as said ones pyscological self is not physical so its illogical to think it can be operated on
why is DBS carried into the future?
because it can provide the researcher with information other research methods can’t
what are ethical issues of early physcosurgery?
valid consent wasn’t always given as physcosurgery was being used on patients in prisons and asylums, however may be argued patients weren’t in correct state of mind to give fully formed consent.
how was the ethical issue of valid consent dealt with in 1983 relating to physcosurgery?
those who were in a mental health asylum but hadn’t committed a crime had the same level f rights to consent as someone who wasn’t detained
what’s another ethical issue of physcosurgery aswell as valid consent?
irreversible damage- effects of physcosurgery cannot be reversed
what were some effects that early physcosurgery cause (irreversible damage)?
significant changes to ones cognitive abilities such as memory loss, and sometimes severe blunting of emotions
what happened to many patients following early stage of prefrontal lobotomies?
zombie like, without emotions
what’s the side effects of modern day physcosurgery like?
risk is reduced a lot more throughout modern day physcosurgery as techniques have developed specific areas of the brain can be targeted more precisely. however DBS still carries risks of long term side effects such as seizures and altered states of mood
