Can chemotherapy cause dementia?

Alzheimer's disease is commonly referred to as senile dementia. Chemotherapy generally does not cause Alzheimer's disease. If significant discomfort occurs after chemotherapy, it is advisable to seek medical attention promptly. Detailed analysis is as follows:

Alzheimer's disease is a neurodegenerative disorder, with common symptoms including memory loss, reduced ability to learn new information, low mood, and others. Chemotherapy is a treatment strategy used to kill tumor cells, aiming to extend life and improve quality of life. The exact cause of Alzheimer's disease remains unclear and may be related to genetic and environmental factors; however, there is no direct causal relationship between the disease's pathogenesis and the side effects of chemotherapy. Therefore, undergoing chemotherapy generally does not lead to Alzheimer's disease.

While chemotherapy drugs are used to kill cancer cells, they may also affect normal cells to some extent, causing certain side effects such as hair loss, nausea, and vomiting. If a patient has Alzheimer's disease, it is recommended to follow medical advice and use medications such as oryzanol tablets, mecobalamin capsules, and monosialotetrahexosyl ganglioside sodium injection as prescribed.

In daily life, patients are advised to maintain adequate sleep and an optimistic, positive mindset, and engage in appropriate physical exercise such as running or walking, which may benefit recovery.
