In many people with epilepsy , it has been observed that when they have an episode of seizure that break out into uncontrolled laugh for no valid cause . It is whole unvoluntary and they do not seem to have a command over it . This is medically term as Gelastic Seizure . It is a very rare variety of epilepsy . These seizures are mostly colligate with behavioural problems and unnatural cognitive development . It has been keep that bulk of the cases of gelastic Seizures recrudesce from hypothalamic hamartomas which are benign passel that consist of gray matter.[1,2,3 ]
In some cases hoi polloi with head-on and temporal lobe lesion have also been observe to have gelastic seizures . With regard to the epidemiology , there is very limited data point in the literature , especially with regard to the adult population . However , according to one study done in London , it has been figure that less 0.8 % of all epilepsy patient role had gelastic seizures.[1,2,3 ]
Sometimes , uncontrolledlaughtermay also be seen in other variants of seizures and thus may go unnoticed.[1,2,3]The article below highlighting some of the causes of uncontrolled laugh in epilepsy .
What Causes Uncontrolled Laughter In Epilepsy?
As express , uncontrolledlaughterin epilepsy is medically termed as gelastic ictus and is an extremely rare form of epilepsy . It is mostly find out in patients with a jazz diagnosis of benignant brain masses that spring up in the hypothalamus called hypothalamic hamartomas . To explore the causes of uncontrolled laugher in epilepsy , researchers from University of Hawaii come across a patient role with a history of gelastic seizures characterized by uncontrolled laugh since childhood.[3 ]
Till the sentence , the man had met the research worker , the condition had remained undiagnosed and uncalled-for to say he had received no treatment for it . He had been experiencing indocile laughter at least two to three times a week since he was 8 eld one-time . When looking at the retiring aesculapian story of this man , it was noted that he was diagnosed withbrain tumor , diabetesand hadschizophrenia . There was also a story of cognitive impairment and behavioural changes.[3 ]
The researchers did an EEG which detected abnormal activity in the good frontotemporal region of the brainiac confirming epilepsy . Further examination with MRI revealed that there was a distinct malformation on the hypothalamus which was reproducible with a hypothalamic hamartoma . All these feature of speech clearly confirmed a diagnosis of gelastic seizures.[3 ]
The episode of unruly laughter was then brought under control by way of medicine which minify the seizure frequency . The researcher believe that it is authoritative to look for epilepsy in mass who pose with strange instalment such as unfitting laughter as effective care can be impart once a cause for the unusual and abnormal behaviour is identified.[3 ]
The route ahead for the researchers is to accentuate the importance of not leave out a potential diagnosis of gelastic seizures , especially in people with unnatural behavior such as an uncontrolled laughter for no valid rationality and confirm the diagnosis with EEG and MRI of the brain.[3 ]
They name that the workup should include imaging with attention to the suprasellar region along with EEG . An accurate diagnosis and proper intervention is the paint to prevent such abnormal behavior as meet in mass with gelastic seizures.[3 ]
