There are multiple causes of confusion in cancer patients. These may include:
Chemotherapy and other cancer treatments: Some medications used to treat cancer can affect the brain and nervous system, leading to cognitive changes. Metabolic imbalances: Abnormal levels of electrolytes, glucose, or other substances in the blood can affect brain function. Infections: Cancer patients are often more susceptible to infections, which can cause inflammation in the brain. Pain and pain medications: Severe pain and the opioids used to manage it can both contribute to confusion. Paraneoplastic syndromes: These are rare disorders triggered by an abnormal immune system response to a cancerous tumor.
