* Ages ≥ 18 and \<89 at time of diagnosis.
* Recently diagnosed with their initial head and neck cancer and able to be consented prior to OR within first week of starting standard of care radiation therapy.
* Baseline simulation whole-brain MRI or CT available as part of standard of care.
* Patients diagnosed with cancer, no distant metastases.
* Karnofsky Performance Status of \>= 70 or comparable ECOG performance at enrollment.
* As per self-report, if currently taking psychoactive medications (excluding gabapentin and including but not limited to antidepressants, and anxiolytics) on a daily basis, dose must have been stable for at least two months prior to enrollment.
* English fluent as per self-reported fluency of "well' or "very well", and having a reasonable comprehension of the study conversation in the opinion of the research staff).\*\* \*\* Language verification: Prior to enrollment, all patients will be asked the following two questions by the CRC to verify English fluency necessary for participation in the study:

  2. What is your preferred language for healthcare? Must respond English.

Exclusion Criteria:

* Patients with multiple primary head and neck cancers, carcinoma of unknown primary, or recurrence.
* Patients who previously received radiation therapy to the head and neck region as treatment for any prior cancer for any other non-cancerous condition.
* Patients who had chemotherapy within two years prior to their recent diagnosis of head and neck cancer, such as patients who received chemotherapy as treatment for any other type of cancer or received neoadjuvant chemotherapy prior to surgery to treat their recent head and neck diagnosis. Patients who receive induction chemotherapy just prior to the start of their radiation therapy or receive concurrent chemotherapy to treat their recent head and neck diagnosis are allowed
* At the discretion of the clinician, patients who are unable to comfortably speak due to symptoms of their cancer or treatment, such as surgery.
* Pre-existing diagnosis of neurodegenerative disorder that affects cognitive function (e.g. Alzheimer's disease, Parkinson's disease, Multiple Sclerosis, Dementia, Seizure Disorders, etc.).
* As per medical record or self-report, history of stroke or head injury requiring medical care, confirmed structural lesion on neuroimaging, and persistent cognitive difficulties impacting work or daily life or required cognitive rehabilitation.
* Pre-existing diagnosis of a Schizophrenia Spectrum Disorder, substance use disorder, Bipolar Disorder or Schizotypal personality disorder. Schizophrenia Spectrum Disorders include Schizophrenia, Schizophreniform disorder, Schizoaffective disorder, Delusional disorder, Brief psychotic disorder, and Attenuated Psychotic Disorder.
* Pre-existing visual or auditory impairment that would preclude ability to complete the assessments (e.g. history of significant macular degeneration or being unable to correct hearing with hearing aids)
