Your memory loss is new? I have memory problems with recall of names of people and physical landmarks but I have had problems with recall for decades.

Causes of memory loss include:

Alcohol or illicit drug intoxication
An event in which not enough oxygen was going to the brain (heart stopped, stopped breathing, complications from receiving anesthesia)
Brain growths (caused by tumors or infection)
Brain infections such as Lyme disease, syphilis, or HIV/AIDS
Brain surgery, such as surgery to treat seizure disorders
Cancer treatments, such as brain radiation, bone marrow transplant, or after chemotherapy
Certain medications
Certain types of seizures
Dementia
Depression, bipolar disorder, or schizophrenia when symptoms have not been well controlled
Dissociative disorder (not being able to remember a major, traumatic event; the memory loss may be short-term or long-term)
Drugs such as barbiturates or benzodiazepines
Electroconvulsive therapy (especially if it is long-term)
Encephalitis of any type (infection, autoimmune disease, chemical/drug induced)
Epilepsy that is not well controlled with medications
Head trauma or injury
Heart bypass surgery
Illness that results in the loss of, or damage to, nerve cells (neurodegenerative illness), such as Parkinson's disease, Huntington's disease, or multiple sclerosis
Long-term alcohol abuse
Migraine headache
Mild head injury or concussion
Nutritional problems (vitamin deficiencies such as low vitamin B12)
Permanent damage or injuries to the brain
Transient global amnesia
