Overview

Mononucleosis
Infectious mononucleosis, often called mono, is a contagious viral infection. It commonly causes extreme tiredness, fever, sore throat, swollen lymph nodes, and sometimes an enlarged spleen or liver. Most cases are caused by Epstein-Barr virus. Symptoms often develop gradually and most people recover, although fatigue can continue for several weeks or occasionally longer.
Premenstrual Dysphoric Disorder
Premenstrual dysphoric disorder (PMDD) is a severe cyclical condition in which emotional, behavioral, and physical symptoms occur during the premenstrual phase and substantially interfere with daily functioning, relationships, work, or other activities. Symptoms typically improve after menstruation begins. PMDD is more severe than typical premenstrual symptoms and commonly includes marked mood changes, irritability, depression, anxiety, difficulty concentrating, fatigue, sleep changes, and physical symptoms.

Diagnosis

Mononucleosis
Diagnosis is based on the symptoms and physical examination, including examination of the throat and lymph nodes and checking for enlargement of the liver or spleen. A healthcare provider may order blood tests to look for changes associated with mononucleosis or antibodies to Epstein-Barr virus. A rapid mono test may be used in appropriate circumstances, although additional testing may be needed when the result is unclear.
Premenstrual Dysphoric Disorder
Diagnosis is based on the timing, number, severity, and cyclical recurrence of symptoms across menstrual cycles and the degree to which they interfere with daily functioning. Prospective symptom tracking over multiple cycles is often used to document the pattern. Evaluation also considers other psychiatric, medical, and gynecological conditions that can cause similar symptoms. There is no single blood test that confirms PMDD.

Prevention

Mononucleosis
There is no vaccine that prevents infectious mononucleosis. The risk of spreading the infection can be reduced by avoiding kissing and by not sharing food, drinks, utensils, or lip balm with someone who has mono. Good hand hygiene is also useful. Because the virus may remain in saliva after symptoms improve, people should follow appropriate precautions during recovery and according to medical advice.
Premenstrual Dysphoric Disorder
There is no guaranteed way to prevent PMDD because it is associated with individual sensitivity to normal hormonal fluctuations. Regular sleep, physical activity, balanced nutrition, and effective stress management may help reduce the impact of symptoms. Tracking menstrual cycles and symptoms can help identify patterns and support early assessment when emotional or physical symptoms repeatedly interfere with work, relationships, or other daily activities.

Risk Factors

Mononucleosis
Mononucleosis is particularly common among teenagers and young adults, although infection can occur at any age. Risk increases with close contact with an infected person because the virus is commonly spread through saliva. Sharing drinks, food, utensils, or personal items that contact saliva can also transmit the infection. Previous lack of exposure to Epstein-Barr virus may make a person susceptible to symptomatic infection.
Premenstrual Dysphoric Disorder
Risk may be increased by a personal or family history of mood disorders, previous significant premenstrual symptoms, and individual sensitivity to normal reproductive hormone changes. Some people may also have coexisting anxiety or depressive disorders. PMDD occurs in people who are biologically sensitive to cyclical hormonal changes, and symptoms may vary over different stages of reproductive life.
