Eight points recommended to explain the diagnosis to the person and their caregivers are:

Reasons for concluding they do not have epilepsy
What they do have (describe FND)
Emphasize they are not suspected of "putting on" the attacks, and the symptoms are not "all in their head"
There may be no triggering "stresses"
Maintaining factors
May improve after correct diagnosis
Caution that anticonvulsant drug withdrawal should be done in conjunction with their physician
Describe treatment to help regain control of symptomsPsychotherapy is the most frequently used treatment, which might include cognitive behavioral therapy or therapy to retrain the physical symptoms and allow the individual to regain control of the attacks (ReACT). There is also some evidence supporting selective serotonin reuptake inhibitor antidepressants.Cognitive behavioral therapy
Cognitive behavioral therapy (CBT) treatments for PNES typically target fear avoidance and work to reattribute patients symptoms to psychosocial issues. Retraining and Control Therapy (ReACT)
ReACT, while new and understudied, has shown extremely promising outcomes for reduction of PNES episodes in pediatric patients. This therapy focuses on the idea that PNES are caused by a learned physical reaction or habit the body develops, similar to a reflex. ReACT aims to retrain the learned reaction (PNES episodes) by targeting symptom catastrophizing and restoring sense of control over symptoms. Prognosis
Though there is limited evidence, outcomes appear to be relatively poor with a review of outcome studies finding that two thirds of people with PNES continue to experience episodes and more than half are dependent on the Social Security program at three-year follow-up.
Differentiated vulvar intraepithelial neoplasia also known as VIN Simplex: is associated with vulvar dermatoses such as lichen sclerosus. It is associated with atypia of the squamous epithelium. Risk factors
The exact cause of VIN is unknown. Studies are being done to determine the cause of VIN. The following factors have been associated with VIN:

HPV (Human Papilloma Virus)
HSV-2 (Herpes simplex Virus - Type 2)
Smoking
Immunosuppression
Chronic vulvar irritation
Conditions such as Lichen Sclerosus

Diagnosis
The person may have no symptoms, or local symptomatology including itching, burning, and pain. The diagnosis is always based on a careful inspection and a targeted biopsy of a visible vulvar lesion. The type and distribution of lesions varies among the two different types of VIN. In the Usual type VIN, seen more frequently in young patients, lesions tend to be multifocal over an otherwise normal vulvar skin. In the differentiated type VIN, usually seen in postmenopausal women, lesions tend to be isolated and are located over a skin with a vulvar dermatosis such as Lichen slerosus. Prevention
Vaccinating girls with HPV vaccine before their initial sexual contact has been claimed to reduce incidence of VIN. References
