Neurological side effects of radiation therapy
Summary
Radiation therapy (RT) can impair neurological functions, particularly cognitive status, in cancer patients. This review details RT
Area of Science:
- Neuro-oncology
- Radiation oncology
- Radiosurgery
Background:
- Radiation therapy (RT) is a primary cancer treatment.
- Technological advancements enhance RT precision, reducing healthy tissue exposure.
- Increased life expectancy raises concerns about patients' quality of life and adverse events.
Purpose of the Study:
- To review the physiopathological processes of neurological damage from RT.
- To describe neurological symptoms and MRI findings post-RT.
- To discuss therapeutic and preventive strategies for RT-induced neurological deficits.
Main Methods:
- Literature review of studies on radiation therapy and neurological outcomes.
- Analysis of physiopathological mechanisms.
- Synthesis of clinical findings, including neurological symptoms and MRI observations.
Main Results:
- RT can lead to various adverse events, notably affecting neurological functions like cognition.
- Specific neurological symptoms and localized MRI modifications are observed following RT.
- Understanding these effects is crucial for managing long-term patient well-being.
Conclusions:
- Neurological adverse events, particularly cognitive impairment, are significant concerns in cancer patients undergoing RT.
- This review synthesizes current knowledge on RT's neurological impact, including mechanisms, symptoms, and imaging findings.
- Effective therapeutic and preventive strategies are essential for preserving patients' quality of life.

01:27Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists
364
5-HT3 receptor antagonists, such as dolasetron, granisetron (Kytril), ondansetron (Zofran), and palonosetron (Axoli), are crucial in managing chemotherapy-induced nausea and vomiting (CINV) and postoperative nausea. These drugs selectively block 5-HT3 receptors in the visceral vagal and spinal afferent nerves, chemoreceptor trigger zone, and the vomiting center. They have a rapid onset of action and can be given as a single dose before chemotherapy. Ondansetron and granisetron, in particular,...

02:59Biological Effects of Radiation
16.2K
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...

01:12Local Anesthetics: Adverse Effects
516
While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...

01:21Skeletal Muscle Relaxants: Adverse Effects
508
Skeletal muscle relaxants are widely used for muscle paralysis and relieving pain following any muscle injury or stiffness. However, depending on the drug type, they can have adverse effects that range from mild to severe. Usually, nondepolarizing neuromuscular blockers have minimal side effects. For example, drugs like d-tubocurarine, cisatracurium, and rocuronium cause hypotension, whereas drugs like baclofen, when stopped abruptly, can lead to the recurrence of spastic conditions.

01:28Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists
280
Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy. SP binds and activates...

01:21Chemotherapy-Induced Nausea and Vomiting: Cannabinoids
386
Tetrahydrocannabinol (THC) is a phytocannabinoid that primarily interacts with the CB1 receptor, a type of G protein-coupled receptor (GPCR) predominantly in and around the chemoreceptor trigger zone (CTZ) and emetic center. THC also blocks the serotonin receptor activity in the dorsal vagal complex (DVC) by inhibiting serotonin release. THC exerts its anti-emetic effects through these interactions, which are beneficial for patients undergoing chemotherapy.
