A subclinical capture is a type of seizure that come with few obtrusive physical symptoms . possible symptoms may be subtle and let in blink or stare into space .
Unlike typical seizure , Dr. can only name subclinical seizures through diagnostic tests like an electroencephalogram ( EEG ) , which measures unnatural brain activeness .
While there may be minimum outward mark , these capture indicate atypical electrical activity in the brain and may still have implications for neurologic wellness .
Symptoms of subclinical seizure
Subclinical seizures typically do not present with the noticeable symptoms that most hoi polloi affiliate with clinicalseizures , such asconvulsionsorloss of awareness .
Symptoms can be vague or absent . This mean that peoplemay not be mindful ofsubclinical seizures until a doctor confirms them using symptomatic tools like EEGs .
Subclinical seizures may include the following types of seizure body process :
What causes subclinical seizures?
concord to a2022 retrospective subject , subclinical seizure may occur among people who grow epilepsy at an early long time .
underlie conditions that disrupt typical brainiac function may also stimulate subclinical ictus . For example , a2021 articleassociated subclinical seizures in infants with several underlying health conditions , including :
Subclinical seizures may also fall out in people who are critically ominous , includingthose in intensive concern social unit ( ICUs ) or acoma .
How common are subclinical seizures?
harmonize to the2022 field of study , the overall preponderance of subclinical seizures is unclear . However , enquiry suggests subclinical seizures are more plebeian in :
The researcher also spotlight that describe preponderance statistics may vary count on the type and length of EEG recording . For example , the sensitivity using intracranial EEG recordings is higher than on scalp EEG recordings .
A2021 articlesuggests that between 1 and 3.5 in every 1,000 newborn baby experience seizure , most of which are subclinical .
A 2021 long - term sketch suggests that subclinical seizure bodily process may fall out in around50%of people withAlzheimer ’s diseasewho have never had a clinical epileptic seizure .
Clinical vs. subclinical seizures
The major difference between clinical and subclinical seizures lie in the seeable strong-arm symptom .
The symptoms associated with clinical seizures may be easier to observe without particular diagnostic prick , although ratification is typically necessary using test such as an EEG orMRI .
Both clinical and subclinical gaining control can have a person to lose awareness . In both type , a person may experience confusion or neutered superstar .
During a subclinical seizure , people may exhibit a deficiency of interaction . Clinical seizures may lay out with more obvious symptoms , such as severe convulsion .
Despite the absence seizure of spastic symptoms , subclinical seizure occur due to seizure activity in the brain and may require treatment to forbid potential complications .
Treatment for subclinical seizures
discourse options may reckon on the implicit in cause of the seizures and the frequency with which they occur . For example , if the seizures are due to temporal lobe epilepsy , healthcare master will expend anti - epilepsy drugs that are indicated for that type of epilepsy .
When subclinical capture take place in infants , doctor may care for with anticonvulsant medications to thin brain injury and excitement .
A2022 articlesuggests thatsurgical treatmentof the subclinical raptus attack geographical zone may have favorable outcomes . The research worker included various character of operating room in this treatment bracket , including resection , stimulation , and laser interstitial thermal therapy .
accord to a2023 article , healthcare pro may plow subclinical seizures less aggressively than clinical seizures . However , the discourse depends on the specific type of subclinical seizure and its anticipated mindset .
In citizenry with persistent subclinical seizure , uninterrupted EEG monitoring also be necessaryto helpevaluate intervention response and adjust medications if necessary , specially in decisive care configurations .
Subclinical seizures outlook
The long - term outlook for someone with subclinical seizures may depend on theunderlying causeand how quickly a health care professional can diagnose and handle the seizures .
In some cases , subclinical seizuresmay persisteven after a doctor effectively treats clinical seizures .
concord to a2022 retrospective study , subclinical seizures may also chair to irreversible harm to a person ’s brain function . For example , they may lead to a faster cognitive decline in people with Alzheimer ’s disease .
The study researchers indicate that immediate direction may be beneficial to result .
When to speak with a doctor
People shouldseek aesculapian adviceif they have signs of clinical seizures .
However , subclinical seizure ordinarily cause less obvious symptom , and people commonly are n’t cognisant of their own ictus . fellowship member , friends , or coworkers may be incognizant the person is having a subclinical seizure and may mistake them as distrait or daydreaming .
Subclinical seizure may occur in hoi polloi with conditions that move typical mental capacity function , such as epilepsy , Alzheimer ’s disease , and head harm . Anyone with one of these conditions or factors should regularly communicate with their healthcare team .
Caregivers may also be able to find out for atypical behaviors in minor with developmental disorder and adults with neurodegenerative diseases and report anything unusual to a doctor .
Summary
A subclinical seizure advert to a raptus that occurs without obvious physical symptom , meaning it does not produce the typical signs people link with capture , such as convulsion or loss of consciousness .
health care master can only affirm this type of gaining control through symptomatic tools like an EEG . People may miss them because they do not attest externally , but these seizures may still indicate atypical psyche function .
Doctors may choose to address subclinical seizures with anticonvulsant medications or surgical process . They will also aim to treat or manage any fundamental conditions that may be causing the capture natural process .
