Yet, sometimes our minds contemplate why do we laugh uncontrollably. Going deeper into the matter, it could probably be because of a medical condition termed as PseudoBulbar Affect (PBA). There are some other medical conditions with a similar symptom, but this is a major symptom for PBA.

Similar medical causes could be:

  • Gelastic seizure
  • ALS (Lou Gehrig’s disease)
  • Kuru (TSEs)
  • Hyperthyroidism
  • Alzheimer’s disease
  • Parkinson’s disease or various other diseases.

The uncontrollable laughing or any emotional outburst is sometimes also regarded as pathological laughing or crying, or involuntary emotional expression disorder.

PseudoBulbar Affect (PBA)

What Does It Mean?

Neurologically, PseudoBulbar Affect (PBA) is when we suffer from a condition where unmanageable laughter or any other emotional outburst keeps occurring without any reason. It happens quite a few times and you don’t know how to stop it. It could be a neurological disease or due to a brain injury.

In the brain, the larger part, cerebrum has a grey matter which in turn has four lobes. These lobes work as a processor to process, interpret, and give out a meaningful perception. Out of the four lobes, the frontal lobe majorly deals with emotions. The other parts of the brain, namely, the cerebellum and the brain stem deal majorly with the motor or sensory functions or give out the reflexes.

During this condition, the frontal lobe and the cerebellum and brain stem get detached. As a result, the detachment between the places where emotions are controlled and where reflexes occur takes place. So, during certain situations, an emotional outburst happens. And, we unknowingly think of, why do we laugh uncontrollably.

  • Presumably, the chemical messengers that send signals across the body, participate to lead to this condition. Serotonin, Dopamine or Norepinephrine are some of the neurotransmitters which are looked at as contributors to PBA.
  • Another reason might be a brain injury where various nerve routes might be in turmoil from certain parts of the brain to the cerebellum. It could lead to unmanageable control over emotional reactions.
