Hypothyroidism, or "underactive thyroid," means that the thyroid gland in the neck does not produce enough of its hormones. This causes a slowing of the body's metabolism.
The condition can occur due to autoimmune disease; any surgery or radiation treatment to the thyroid gland; some medications; pregnancy; or consuming too much or too little iodine. It is often found among older women with a family history of the disease.
Common symptoms include fatigue, constantly feeling cold, weight gain, slow heart rate, and depression. If left untreated, these and other symptoms can worsen until they lead to very low blood pressure and body temperature, and even coma.
Diagnosis is made through a simple blood test.
Hypothyroidism is easily managed with daily oral medication. The patient usually starts feeling better after a couple of weeks and may even lose some extra weight.

Brain tumor or mass
In medical terms, "mass" and "tumor" mean the same thing: the unexplained, out-of-place growth of tissue anywhere in the body, including the brain.
The cause of any sort of brain tumor is unknown. Some originate in the brain, while others spread from cancers growing in other parts of the body.
Symptoms may include increasing headaches; nausea and vomiting; blurred or double vision; loss of sensation in an arm or leg; loss of balance; confusion; speech difficulties; or seizures.
If symptoms persist, it is important to see a medical provider so that any treatment can begin as soon as possible.
Diagnosis is made through neurological examination, CT scan, and/or MRI.
If the mass or tumor is found to be benign, that means it is not cancer and not harmful. It may or may not be treated.
If it is malignant, that means it is cancer and must be treated. This will involve some combination of surgery, radiation therapy, and chemotherapy, followed by specialized therapy to help with recovery.

FAQs about forgetfulness
Why do I have sudden forgetfulness and confusion?
Sudden forgetfulness and confusion can be a sign of dehydration. As you stand, especially if you have been sitting for an extended time, you may have a decrease in blood flow to your brain. Low blood flow may cause dizziness, confusion, and even small bouts of forgetfulness. If the forgetfulness and confusion persists or recurs, seek medical evaluation.
Can headaches cause forgetfulness?
No, headaches themselves do not commonly cause memory loss. Memory loss is a serious symptom that can be caused by a process affecting the brain. A headache and memory loss can be signs indicating a stroke. If you are experiencing headache and associated memory loss, you should seek medical evaluation.
Why am I so forgetful when I'm pregnant?
Currently, we do not know why pregnancy affects cognitive function. A large analysis of prior studies showed that memory, executive functioning, and mood were negatively affected during pregnancy. Currently, untested hypotheses attribute this to the stress of caring for and carrying a child. Additionally, the increase in hormones present during pregnancy may affect memory.
Is forgetfulness a sign of anxiety?
Yes, forgetfulness or memory problems may be a sign of anxiety. Anxiety and worry use mental faculties that are then unavailable to both commit items to memory and to learn new skills. While some stress is useful to increase functioning, excess stress and anxiety may leave an individual unable to rest and contribute to poor performance and burnout.
Why am I tired and forgetful all the time?
Fatigue and memory loss are common symptoms across the lifespan and may be attributable to many diagnoses. The most common cause of fatigue and memory loss is sleep deprivation. An insufficient quantity or quality of sleep can have a serious effect on short term memory and can lead to fatigue and a lack of attention throughout the day.
