- Explain what is neuroplasticity and why is this important in the case of Phineas Gage?arrow_forwardWhy do you think it has been so difficult to identify genes underlying schizophrenia? Rachel asked to see a genetic counselor because she was concerned about developing schizophrenia. Her mother and maternal grandmother both had schizophrenia and were institutionalized for most of their adult lives. Rachels three maternal aunts are all in their 60s and have not shown any signs of this disease. Rachels father is alive and healthy, and his family history does not suggest any behavioral or genetic conditions. The genetic counselor discussed the multifactorial nature of schizophrenia and explained that many candidate genes have been identified that may be mutated in individuals with the condition. However, a genetic test is not available for presymptomatic testing. The counselor explained that based on Rachels family history and her relatedness to individuals who have schizophrenia, her risk of developing it is approximately 13%. If an altered gene is in the family and her mother carries the gene, Rachel has a 50% chance of inheriting it.arrow_forwardIt has been demonstrated that the memories of mice can be improved by genetically engineering their genomes to include an extra copy of a gene called NR2B. The protein product of this gene functions as a receptor in the neurons of many vertebrates. For which type of human diseases might this discovery prove important in the development of a therapy? How do you know? ·arrow_forward
- A consumer survey has highlighted a major increase in the use of Pregabalin, an authorised antiepileptic drug. The working hypothesis is that this drug is being used in other pathologies, such as to treat neuropathic pain. What sort of indicators could we use to obtain information that might enable us to test this hypothesis? Select one: O a. The conducting of a controlled clinical trial enabling us to assess the efficacy of Pregabalin in neuropathic pain. O b. The construction of drug-indication indicators (studying consumption in terms of the indication for which it is prescribed). O c. The construction of indicators that relate the drug to the indication and the treatment outcome. O d. A comparison between the consumption of Pregabalin in defined daily doses per 1000 inhabitants per day and the diagnosed prevalence of epilepsy.arrow_forwardThe biogenic amine hypothesis of schizophrenia suggests: Question 43 options: a) That changes in presynaptic neurotransmitter release, and postsynaptic receptor sensitivity, underlies the pathologic process in schizophrenia b) That a decrease in the amount of glutamate in the brain underlies the pathological process in schizophrenia c) That dysfunctional parenting in early childhood is an underlying pathological process towards the development of schizophrenia d) That highly expressed emotion, negative communication patterns, and emotionally involved families increase dopamine release, thereby causing schizophreniaarrow_forwardWhich statement about correlation and causation is true? (a) A correlation is never a causation. (b) Correlation sometimes indicates causation. (c) A correlation is more difficult to establish than a causation. (d) Correlation always implies causation.arrow_forward
- Name three families of drugs used to treat depression.arrow_forwardElectroconvulsive therapy (ECT) is a reasonable option for intractable depression or schizophrenia, but a mechanism of action has not been established. One credible hypothesis is related to neural plasticity. Below is the neuronal gene expression assay for four genes after ECT, normalized with the Hamilton depression rating scale of 21 items version (HAM-D-21). Which of the following conclusion you may NOT conclude from the data? ECT may convert adult neurons into IPSCs which may divide and differentiate into healthy adult neurons Neural plasticity steadily increases with the number of ECT administration ECT seems to increase the expression of Yamanaka’s four transcription factors ECT may increase neural plasticityarrow_forwardWrite notes on clinical strategies for the treatment of (a) Huntington's disease and (b) amyotrophic lateral sclerosis. Include one example of a novel therapeutic strategy currently being investigated for each of these diseases.arrow_forward

Question 45 options: a) Poverty of speech; lack of initiative b) Anhedonia; flat affect c) Erotomania; social withdrawal d) Avolition; reduced hygienearrow_forward5arrow_forwardWhile visiting the Center for Addiction and Mental Health (CAMH) in Toronto, you have the rare opportunity to observe a client with schizophrenia during a PET scan. The client is a chronic user of cannabis and was asked to use cannabis 15 minutes before the scan took place. What is likely to be observed from the PET scan? Question 59 options: a) Reduced activity in the globus pallidus b) Increased activity in the limbic system c) Increased glucose metabolism in frontal lobe d) Increased size of hippocampusarrow_forward
