Some of the most common naturally occurring brain toxins that lead to neurotoxicity as a result of long term drug use are amyloid beta (Aβ), glutamate, dopamine, and oxygen radicals. When present in high concentrations, they can lead to neurotoxicity and death . Some of the symptoms that result from cell death include loss of motor control ...
Second, the drug dose the patient received, and if its amount is commensurate with developing CIPN, must be considered. [1] The immunomodulatory drug bortezomib, for example, is more likely to cause neurotoxicity in a cumulative dose of 20 grams. Finally, the characteristics and the duration of a patient's symptoms should be analyzed.
Cardiotoxicity is the occurrence of heart dysfunction as electric or muscle damage, resulting in heart toxicity. [1] This can cause heart failure, arrhythmia, myocarditis, and cardiomyopathy in patients. [2] Some effects are reversible, while in others, permanent damage requiring further treatment may arise. The heart becomes weaker and is not ...
A monoamine neurotoxin, or monoaminergic neurotoxin, is a drug that selectively damages or destroys monoaminergic neurons. [1] Monoaminergic neurons are neurons that signal via stimulation by monoamine neurotransmitters including serotonin , dopamine , and norepinephrine .
Alpha 1 blockers cause vasodilation by relaxing smooth muscles that control blood vessel diameter, leading to lower blood pressure. [1] FDA-approved uses of these drugs include treating conditions like benign prostatic hyperplasia , hypertension , pheochromocytoma , extravasation management, and reversal of local anesthesia .
Local pathology of neurotoxin exposure often includes neuron excitotoxicity or apoptosis [14] but can also include glial cell damage. [15] Macroscopic manifestations of neurotoxin exposure can include widespread central nervous system damage such as intellectual disability , [ 5 ] persistent memory impairments, [ 16 ] epilepsy , and dementia ...
Olney's lesions, also known as NMDA receptor antagonist neurotoxicity (NAT), is a form of brain damage consisting of selective death of neurons but not glia, observed in restricted brain regions of rats and certain other animal models exposed to large quantities of psychoactive drugs that inhibit the normal operation of the neuronal NMDA receptor.
Plaques in the walls of the coronary arteries can rupture, resulting in occlusion of the artery and deprivation of blood flow and oxygen to the heart muscle, resulting in cardiac cell death. [9] This is known as myocardial infarction. [9] A heart attack can cause arrhythmias, as well as permanent damage to the heart muscle. [25]
