What does risperdal do to your brain?
this is according to my nursing drug handbook: 2005Mosby's nursing Drug Reference, page 908. It is a antipsychotic med. the action of the drug is unknown, but may be medicated through both DOPamine type 2 and serotinin type 2 antagonism. it sounds to me that pretty much this is saying that it may be blocking the dopamine and serotonin secretions with in the brain, but is really unknown, so it would be best to ask your doctor or pharmacist.
ANOTHER RISPERDAL ANSWERAccording to my medical textbook the answer is as follows: "While the exact mechanism of action of risperidone (risperdal) is unknown, it appears to alter the activity of certain chemicals in the central nervous system to produce a tranquilizing and antipsychotic effect".

What is true concerning a mild traumatic brain injury?
Acquired brain injury (ABI) is characterised as a brain injury which has occurred after birth, and is not the cause of any genetic or congenital disorder. A "mild" ABI could be considered as a brain injury which does not have a profound impact on the brain functioning or the sufferers behaviour, or could be considered as temporary.
What are the part to the brain stem?
Starting from the bottom and moving up: The Reticular formation, Medulla oblongata, and the Pons. In addition, the cerebellum is next to the brain stem behind the pons, which is why it is also referred to as the "hind brain".
Which lobe of the cerebral cortex would the auditory area?

Controlling essential body functions like heartbeat and breathing.

What drugs act directly on the brain?
There are many to list, but any drug that works on the Central Nervous System (CNS) will effect the brain. Because there are many drugs that fall into that category, I will list the top few that come to mind....those used to treat major psychiatric disorders such as thought disorders, affective disorders and anxiety disorders. First, the thought disorders, such as schizophrenia, dementia and delirium. Aricept (donepezil) is a cholinesterase inhibitor used to treat Alzheimers disease, and its mode of action is to enhance acetylcholine by blocking the enzymes that break it down. Antipsychotics such as Haldol (haloperidol), Zyprexa (olanzapine), Seroquel (quetiapine), and Risperdal (risperidone) work by decreasing Domamine levels. If you look at affective disorders (depression and bipolar), you will find the SSRI's --Celexa (citalopram), Cymbalta (duloxetine), Prozac (fluoxetine), and Zoloft (sertraline). These work by enhancing neurotransmitter (specifically seratonin). Mood Stablizers such as Lithium, Depakote (valproate) and Tegretol (carbamazepine) all act to slow neuronal transmissions. Finally, the anti-anxiety meds (anxiolytics). Meds such as benzodiazepams -- Xanax (alprozolam), Klonapin (clonazepam), and Ativan (lorazepam) -- work to enhance GABA, which calms people down.
Is the brainstem the reptilian brain?
