What are Nocturnal Seizures?
Nocturnal Seizure is a type of seizure disorder where a person experience seizures while sleeping . If the affected role experiences more than 90 % of seizure when at peace , then the patient role is said to have sleep seizures or nocturnal seizures . There are some coarse type of epilepsy such as frontal lobe epilepsy , which can manifest in a nocturnal land . Nocturnal seizure can occur if the eccentric of epilepsy triggers seizures only when the patient is sleeping or if the affected role commonly has seizures during that picky time . In the latter case , if the patient stay awake at a time when he / she normally sleeps , then the affected role can get a seizure while awake . In such vitrine , it is important for the patient role to survey proper dormancy habits . Any type of diversion from normal sleep patterns may trigger frequent seizures in patients who are diagnose with nocturnal raptus or epilepsy , even when the affected role is awake . Some patient role have exclusive nocturnal seizures , i.e. seizures when sleeping ; whereas some patients will have both daytime as well as nocturnal seizure . Around 10 – 40 % of patients suffering from epilepsy will experience seizure exclusively or primarily during sleep or when they are slumber deprived .
Nocturnal seizures or raptus while catch some Z’s greatly touch a person ’s power to get a good night ’s sleep . However , other rest disorders can also produce similar symptom , which can be misdiagnosed as nocturnal seizures or capture while sleep . This is because sleep disorders and ictus , which occur at night , usually occur without the patient ’s knowledge . For right diagnosis of a true nocturnal seizure , it is important to discover the signs and symptoms of a nocturnal seizure or seizures while slumber .
Signs & Symptoms of Nocturnal Seizures
Inability to Concentrate : Patient suffering from nocturnal seizure or seizures while catch some Z’s has inability to concentrate on any type of project . Many sleep disorderliness tend to cause trouble in focusing and undue daytime weariness and dead on target nocturnal gaining control greatly reduce the meter which is spent in abstruse sleep and this leads to drastic effects on the patient ’s wellness and lifestyle . In some patients , nocturnal seizure can cause complete unfitness to function or work during the day .
Involuntary Movement : Nocturnal seizures or seizure while sleeping may induce symptom of uncontrollable or abnormal movement during sleep . In some cases , the patient wake up up of a sudden multiple times without any cause . Some patient suffering from Nocturnal seizures or seizures while sleeping can feel violent bat crusade in the arms and legs when slumber . Upon waking up , the patient wakes up disoriented and fuddle .
Tongue Biting and Incontinence : Nocturnal seizures or seizures while sleeping can cause symptoms of loss of ability in check the muscular tissue of the consistence , which leads to incontinence and accidents in bed . Patient can also have a tendency to bite the natural language . To determine whether the affected role is having true nocturnal seizures or another type of quietus disorderliness , EEG i.e. brain wave activity run and eternal rest subject area are done for right diagnosis .
Other Symptoms of Nocturnal Seizures or Seizures While Sleeping : Nocturnal gaining control can stimulate other type of symptoms or situation for a patient , such as upon waking up the patient role will be having a headache , there can be bed wetting , biting of the tongue , injury to a joint or os , lightheadednessand muscle weakness / strain . Nocturnal seizure or seizures while catch some Z’s can also produce some unusual eccentric of mental behaviour in a affected role . In some cases , object present near the bed will be chance down on the floor , or the patient can find himself / herself on the floor after falling down from layer from nocturnal seizures or gaining control while log Z’s . Children suffer from nocturnal seizures can see strange sleepiness , signs of drooling , headache , regurgitation and bed - wetting .
Causes & Trigger Factors of Nocturnal Seizures
Nocturnal Seizures or Seizures While Sleeping have Due to Sleep neediness : Lack of sleep or sleep neediness is one of the major trigger factor for seizures . nap loss or lose quietus may trigger seizures . patient with nocturnal seizures will have daytime drowsiness , which in play increase the risk of day gaining control in patient with nocturnal seizures or seizures while catch some Z’s .
Nocturnal Seizures or Seizures While log Z’s Caused Due to Changes in Brain Electrical Activity : Nocturnal seizures are believe to occur due to change in the electrical activity in the mastermind in the level of quiescency and awakening . Many of the time , nocturnal seizure are fond seizure .
Epilepsy : Certain types of epilepsy are point to be bear on to nocturnal seizures and these are : Awakening grand mal epilepsy , juvenile myoclonic epilepsy , benignant rolandic epilepsy ( benign focal epilepsy of puerility ) , landau - kleffner syndrome ( LKS ) , electrical condition epilepticus of sleep and frontal onslaught seizures .
Fever & Stress : If the affected role is induce gamey fever or suffers from excessive accent , then it can also trigger gaining control include nocturnal seizures in the affected role .
Nocturnal Seizures or Seizures While Sleeping cause Due to Use of Stimulants : patient suffering from exuberant daytime drowsiness tend to take input , such as coffee to overcome this trouble ; however , this habit can worsen seizure , specially if the excitant is used in large quantity .
Use of Sedatives : person with interrupted quietus or catch some Z’s difficulties may use sedatives , which in turn can aggravate the problem of nocturnal seizures .
Pathophysiology of Nocturnal Seizures
There are many stages of sleep . Most of the nocturnal seizures or seizures while sleeping occur when the patient is in the stagecoach of light sleep , which instantly occurs after fall benumbed , before fire up up or when waking during the dark . This particularly happens in cases of myoclonic seizures , temporal lobe ictus and atypical absence seizure seizures . The mechanism of nocturnal seizures or seizures while sleep is not clearly understand , however , it is believed that sleep bodily function can determine seizures . It is thought that the change of state has an influence on the epileptic activity . Many changes also occur during sleep . Some types of seizures also occur primarily at specific clip of the sleep cycle .
Our brain wave remain quite constant during sleeplessness ; however , many changes fall out during sleep . When we sleep , the brainwaves get transformed from wakeful state to drowsiness , then to light sleep to abstruse rest and then to Rapid Eye Movement ( REM ) rest . This oscillation gets repeated about 3 - 4 times in a night . When there is any change or disturbance in this eternal rest cycle , it results in quite dramatic changes in our brainwaves , i.e. EEG . A person can have nocturnal seizures or seizures while sleep at any time during this rest cycle per second , however , legal age of them happen during unclouded sleep , i.e. stagecoach 1 and 2 of the eternal sleep .
The time when the nocturnal seizures or ictus while sleeping more commonly and frequently occur include :
Changing of Nocturnal Seizures to Daytime Seizures
If the patient has a radiation pattern of having seizures only during nap and this radiation diagram stay for many years , then the chance of having the seizures during day or wakefulness is less . Most of the nocturnal seizure or ictus while sleeping are tonic water - clonic , however , patient can also have focal seizures during eternal sleep .
Facts about Sleep & Nocturnal Seizures
Diagnosis of Nocturnal Seizures
It is difficult to diagnose nocturnal seizures or seizures while sleeping , as the patient may not be aware that they have a capture disorderliness . The involuntary bowel movement of nocturnal ictus or capture while sleeping may appear as distinctive movement of a normal quietus to onlookers . People suffering from nocturnal capture will see different character of situation upon waking up , such as bottom wetting , headache , biting of the clapper , wound to a joint or ivory , muscle impuissance / strain and lightheadedness .
Some patients may have foreign genial doings after make nocturnal seizure . Sometimes , object which are present near the bed will be knocked down to the floor , or the patient role himself can strike down and wake up on the floor .
Risks of nocturnal seizures or seizure while sleeping include asphyxiation , concussion , and SUDEP . It is difficult to measure the duration of the nocturnal ictus .
Nocturnal seizures or seizures while sleeping can also be befuddle or misdiagnosed with parasomnia , which is a term bespeak group of sleep disorderliness , such as teeth comminute , noctambulation and restless branch syndrome . A number of factors are evaluated to diagnose epilepsy and nocturnal capture and these include :
Safety Measures for Patients Suffering from Nocturnal Seizures
Treatment & Management of Nocturnal Seizures
It is an acceptable fact that want of sopor or eternal sleep deprivation acts as a trigger factor for seizures and increase the likelihood for seizures . There can be important break or disturbance of nap due to nocturnal seizures or seizures while slumber .
The purpose of treatment for nocturnal seizures or seizures while sleeping is optimal control of ictus , as they are closely related to kip . Patients suffering from nocturnal seizure will often have partial - onset seizures and these can be well controlled with medications . So , medication is the first - personal credit line of treatment for nocturnal seizures . Medicines , such as anti - convulsants are used to treat nocturnal epilepsy or nocturnal seizures just like other types of epilepsy . The treatment for nocturnal seizures or gaining control while sleeping is almost the same as handling for daytime seizures ; however , in some case the doctor may dictate a higher dose of antiepileptic medication in the even . The treatment of capture and its termination depend on the case of seizures more than the time of natural event of the capture .
Even though the anti - convulsant medicines are effective in treating nocturnal gaining control or capture while sleeping , these medicines can interrupt the patient role ’s dormancy pattern . This in turn increases the likeliness for epileptic symptom , as it is important to get relaxing and undisturbed sleep for patients abide from nocturnal seizures to lessen the chances of further episodes of seizure and to prevent exacerbation of epileptic symptom . It is important to maintain good eternal rest pattern , as it assist in decreasing the epileptic symptom . So , it is important to come up an anti - convulsant medication , which does not agitate the patient role ’s sleeping social system . This will help in minimizing nocturnal seizures and epileptic symptoms . Some of the anti - convulsant medications , which serve in achieve this include : Phenytoin , Phenobarbital , Carbamazepine , Ethosuximide , Valproate , Gabapentin , Felbamate , Lamotrigine , Vigabatrin , Topiramate , Levetiracetam , Tiagabine , Oxcarbazepine and Zonisamide . Oxcarbazepine has the minimal inauspicious effects on a patient role ’s slumber figure . This medicine is also shown to enhance the slow wave - sleep and the persistence of sleep in patients with seizures .
It is important that the patient follow unconstipated quietus habits , especially patient role who have sleep related to seizures . patient role who are having difficulty in falling deceased can overcome this job by increasing the dose of the eve medication , by indulging in serene and reposeful activities in the even , by using rest techniques , by avoiding stimulants , peculiarly in former afternoon or evening and by behavioral training , which will aid in establishing an effective sleep pattern . It is authoritative that the affected role stick to a regular sleep procedure for which sleep specialists can avail .
