The details of PCCI's causes and boundaries are not well known. [7] Two major theories have been advanced: [4] the direct effect of chemotherapy drugs on the brain, and the role of hormones in nervous system health. PCCI is complex and factors other than the chemotherapeutic agents may impact cognitive functioning.
These side effects are serious and some of them are permanent, and many remain a crucial concern for companies and healthcare professionals and substantial efforts are being encouraged to reduce the potential risks for future antipsychotics through more clinical trials and drug development.
PVCs can be distinguished from premature atrial contractions because the compensatory pause is longer following premature ventricular contractions, in addition to a difference in QRS appearance. [20] In some people, PVCs occur in a predictable pattern. Two PVCs in a row are called doublets and three PVCs in a rows are triplets.
Neuroleptic malignant syndrome (NMS) is a rare [5] [6] but life-threatening reaction that can occur in response to antipsychotics (neuroleptic) or other drugs that block the effects of dopamine. [ 1 ] [ 7 ] Symptoms include high fever , confusion, rigid muscles, variable blood pressure, sweating, and fast heart rate. [ 1 ]
Other intravenous anesthetic drugs such as midazolam or propofol may be used. [1] [2] Drug-induced comas are used to protect the brain during major neurosurgery, as a last line of treatment in certain cases of status epilepticus that have not responded to other treatments, [2] and in refractory intracranial hypertension following traumatic ...
The antiemetic medications can block the binding site on a chemoreceptor in the CTZ, so that the emetic agent cannot bind to it to cause its emetic effects. [6] Another way that antiemetic medications can work is by binding to a chemoreceptor in the CTZ, but instead of initiate vomiting, the medication can cause the receptors to send signals to ...
The causes of persisting symptoms are a combination of pharmacological factors such as persisting drug induced receptor changes, psychological factors both caused by the drug and separate from the drug and possibly in some cases, particularly high dose users, structural brain damage or structural neuronal damage.
Symptoms are thought to arise from transient abnormalities in the blood vessels of the brain. [1] In some cases, it may be associated with childbirth, vasoactive or illicit drug use, or complications of pregnancy. [1] If it occurs after delivery it may be referred to as postpartum cerebral angiopathy.
