"PBA" is a symptom of M.S that is simply defined as: "episodes of uncontrollable laughing or crying".
To elaborate more: it's the sudden episode of laughter or crying that goes to 5 or 10 minutes.

It's a very embarrassing symptom and usually misunderstood by most people; the problem is it happens mostly during stressful situations, as in business interviews or serious talks (the higher the stress; the higher the chance of it happening).

I finish this post by copying from "MS Trust" article:

"
Pseudobulbar affect is a physical disorder that results from a disturbance in how you express your emotions, rather than of your actual feelings themselves. Whilst you may be laughing or crying uncontrollably, you may not actually be experiencing any corresponding inner feelings of happiness or sadness. Sometimes the laughing or crying may start in response to something funny or sad you've seen or experienced, but the feelings are usually much more intense, last longer than expected and it may be difficult, or impossible, for you to stop laughing or crying. Some people with PBA find they have episodes where they become excessively angry or frustrated.

You may find it embarrassing if you have these outbursts, particularly if they happen at inappropriate times, or in situations that other people don't find sad or funny. You may worry about it happening again. This can lead to people avoiding social interactions or can affect relationships if you feel you are embarrassing family and friends.

Frustrating :( that is all I can say, and reminds me a lot with Batman's Joker :D
