SEIZURES AND EPILEPSYBy: Qhasmirabt Abu Hazir
DEFINITIONSSEIZURES- clinical event in which there is sudden disturbance of neurological fx caused by an abnormal or excessive neuronal dischargeEPILEPSY- recurrent, unprovoked seizures.
EPILEPSIES25-30%  of these children have other neurological disorder (mental handicap, cerebral palsy)Diagnosed clinically, hence a detailed description of events experienced by patient or an adequate account by a reliable witness is crucialEpilepsy should be viewed as a symptom of an underlying neurological disorder and not as a single entity
RISK FACTORSHx of previous seizuresRecent withdrawal of anti-convulsant medicationBrain tumorNeurodegenerative disorderHx of remote neurologic insult ( stroke, intracranial hemorrhage,cerebral palsy, head, trauma,meningitisFamilial hx of seizures

PARTIAL SEIZURESSIMPLE- Consciousness preservedPARTIALOriginate focally in cortexCOMPLEX-impaired concsiousnessSECONDARILY GENERALIZED
MANIFESTATION OF PARTIAL SEIZURESManifestation will depend on the part of the brain where the discharge originatesTEMPORAL LOBE-the most common-may result in strange warning feelings or aura with smell and taste abnormalities and distortion of sound and shape.-lip smacking, plucking at one’s clothing, and walking in non-purposely manner (automatism)-dejavu-consciouness can be impairedFRONTAL SEIZURESInvolve motor cortex
May lead to clonic movement, which may travel proximally
Asymmetrical tonic seizures can be seen, which may be bizarre and hyperkinetic and can be mistakenly dismissed as non-epileptic eventsOCCIPITAL SEIZURES-cause distortion of visionPARIETAL LOBE SEIZURES- Cause contralateraldysaesthesias (altered sensation), or distorted body image
SITUATION 1"I almost enjoy them. The feeling of déja vu, as if I've lived through this moment and I even know what's going to be said next. Everything seems brighter and more alive." "It is a pressure that starts in my stomach, then rises to my chest and throat. When it reaches my chest, I smell an unpleasant odor of something burnt. At the same time I feel anxious."
SIMPLE PARTIAL SEIZUREConsciousness not impaired
Clinical symptoms include motor, sensory,psychic or autonomicMOTORChange in muscle activity
For example:
Jerking of finger or stiffening of part of the body
Movement may spread (affect one side or extend to both sides)
Weakness affecting speech
Coordinated action such as laughter or automatic hand movements (aware or not)SENSORYChange in any of the senses
For example:
Smell or taste things that aren’t there
Hear clicking,ringing or person’s voice when there is no actual sounds
Feel sensation of “pins and needle”/numbness
Feel floating or spinnig in space
Visual hallucination AUTONOMICChanges in the part of the nervous system that automatically controls body fx
 for example:
Strange or unpleasant sensation in stomach, chest,or head
Change in heart rate
Sweating
Goose bumpsPSYCHICChange in thinking,feeling or experiencing things
For example:
Problem with memory
Inability to find right word
Trouble in understanding spoken or written language
Sudden feeling of emotion like fear,depression or happiness
Feeling of dejavu (I’ve been through this)
Feeling of jamais vu (this is new to me)SITUATION 2“Micky's spells begin with a warning; he says he's going to have a seizure and usually sits down. If I ask him how he feels, he just says 'I feel it.' Then he makes a funny face, a mixture of surprise and distress. During the seizure he may look at me when I call his name but he never answers. He just stares and makes odd mouth movements, as if he's tasting something. Sometimes he'll grab the arm of the chair and squeeze it. He may also pull at his shirt as though he's picking lint off of it. After a few minutes, when he's coming out of it, he asks a lot of questions. He never remembers his 'warning' or these questions. The seizures make him tired; if he has two in the same day, he often goes to sleep after the second one."
COMPLEX PARTIAL SEIZURESCOMPLEX PARTIAL SEIZUREConsciousness impaired
Temporal lobe epilepsy is the most common type
The patient stops what he or she doing and stare blankly, often making rhythmic smacking movements of the lips or displaying other automatism, such as picking at their clothes
After few minutes return consciousness, may initially feel drowsy
Aura may present: alterations of mood, memory
Complex hallucinations of sound, smell, taste,vision,emotional changes (fear,sexual arousal) or visceral sensation (nausea, epigastric discomfort) may also occur.SITUATION 3The seizures start with a tingling in my right thumb. In seconds, my thumb starts jerking. Soon, my whole right hand is jerking. I have learned that by rubbing and scratching my forearm I can sometimes stop the seizure. Other times the jerking spreads up my arm. When it reaches my shoulder, I pass out and people tell me that my whole body starts to jerk.
SECONDARILY GENERALIZED ( “JACKSONIAN” SEIZURES)When partial seizures spread to involve the whole brain and produce generalized tonic-clonic seizures.

myoclonicSITUATION 4Junsu, a 7-year-old boy, often "blanks out" anywhere from a few seconds to 20 seconds at a time. During a seizure, Junsu doesn't seem to hear his teacher call his name, he usually blinks repetitively, and his eyes may roll up a bit. During shorter seizures, he just stares. Then he continues on as if nothing happened. Some days Junsu has more than 50 of these spells
TYPICAL ABSENCE (4-6 years of age)Brief loss of environmental awareness ( LOC), with an abrupt onset and termination, unaccompanied by motor phenomenona except for some eye fluttering and minor alteration in muscle tone or simple automatism such as head bobbing and lip smacking
Can often be precipitated by hyperventilation and lasted for few seconds
 primary generalised absence/petit mal@Stoppage of activity, staring and alteration of concsiousness and may include automatism
TONICSustained contraction or stiffness
Generalised increase in muscle toneCLONIC- Rythmic jerking of one limb, one side or all of the body
SITUATION 6"These seizures frighten me. They only last a minute or two but it seems like an eternity. I can often tell Jessica's going to have one because she acts cranky and out of sorts. It begins with an unnatural shriek. Then she falls, and every muscle seems to be activated. Her teeth clench. She's pale, and later she turns slightly bluish. Shortly after she falls, her arms and upper body start to jerk, while her legs remain more or less stiff. This is the longest part of the seizure. Finally it stops and she falls into a deep sleep."
TONIC-CLONICRhythmical contraction of muscle groups following the tonic phase
In the rigid tonic phase, children may fall to the ground, sometimes  injuring themselves. They do not breathe and become cyanosed.
this is followed by clonic phase, with jerking of the limbs. Breathing is irregular, cyanosis persists and saliva may accummulate in the mouth.
There may be biting of tongue and incontinence of urine

Identification of the type of seizure involved. Determination of whether the seizure disorder falls within a recognized syndrome. A clinical evaluation in search of the cause of the epilepsy. Based on all previous findings, selection of the most appropriate therapy.

    Situation 1Junho couldfeel it. He was in the middle of an exam and didn't want to make a scene, so he tried to control it. But it was no use. The stress of the exam was getting to him, and the longer he held in his tic, the more he could feel it building up inside him. Finally he had no choice but to let it out. It wasn't as bad as he anticipated — his shoulders jerked slightly and no one seemed to notice.

    Situation 3Emily Stevens*is afraid to do the ordinary things most of us take for granted. For years, she has been afraid to drive a car, be active in sports or even walk to the grocery store. Ever since Emily was diagnosed with epilepsy as a child, the constant threat of seizures - with loss of body control and consciousness - has made this 41-year-old woman a prisoner in her own home.As a child, Emily experienced sexual abuse and extreme emotional trauma. As an adult, she again became a victim, but this time of rape. To deal with the horror in her life, Emily learned a long time ago to keep her emotions and feelings to herself.When even large doses of epilepsy medications couldn't stop all her seizures, Emily went to the University of Michigan Epilepsy Clinic. It was not long before Linda Selwa, M.D., medical director of the Adult Neurology Outpatient Clinic, discovered that Emily's problem was not only epilepsy, but a recently discovered condition called pseudoseizures.

    PSYCHOGENIC NONEPILEPTIC SEIZURES/PSEUDOSEIZUREParoxysmalepisodes that resemble and often misdiagnosed as epileptic seizurePNES are psychological (emotional,stress-related) in originDo not result from an abnormal electrical discharge from the brainPNES-commonly misdiagnosed as epilepsy in patient with previous diagnosis of epilepsy that does not respond to drugPsychiatric disorderThe diagnosis requires an inpatient admission where the patient is continuously monitored by both an electroencephalogram (EEG) and video camera

    FEBRILE CONVULSIONBy :Adam Safin bin Abdul Mutti
  • 160.
    History (example)…“Raju wasjust 14 months old. He caught a bad cold from one of the children in the playgroup. He had a fever and runny nose. He was taking a nap when I heard this strange banging sound. I ran into his room, and his whole body was stiff and shaking. The whole thing probably lasted less than 10 minutes. They were the longest 10 minutes of my life. He has never had another one, and doesn't need any seizure medication."

    Definition“ A seizureassociated with fever in the absence of another cause and not due to intracranial infection from meningitis or encephalitis” [ Illustrated Textbook of Paediatrics, 3rd edition].Occur in children between 3 months old and 6 years old.
  • 162.
    Some information…Occur in3% of children between the ages of 6 months and 5 years.Has a genetic predisposition; 10% risk if the child has a first-degree relative with febrile seizures.
  • 163.
    Why it iscommon in children???Seizure threshold is low in children.Viral infection (predominant causes)  rapid increase in temperature  can’t tolerate well  seizures.

    How to differentiatemeningitis and febrile seizure in children???Sign and symptom of meningitis :Headache.Irritability.Nausea.Photophobia.Nuchal rigidity.Positive Kernig and Brudzinski sign (> than 12 months old child).
  • 166.
    Continue…There are signof increase intracranial pressure in meningitis, not in febrile seizure :Bulging fontanelle.Ptosis.Sixth nerve palsy.
  • 167.
    Recurrent Febrile Seizures30-40%of children will have recurrent febrile fits.Risk factors :Early age of onset (less than 15 months old).Epilepsy in first degree relatives.Febrile fits in first degree relatives.Low degree of fever (less than 40°C) during first febrile fits.Brief duration between onset of fever and initial fits.
  • 168.
    Why Children NeedAdmission???Main reason :To exclude intracranial pathology.Fear of recurrent fits.To treat or investigate the cause of fever besides meningitis or encephalitis.To allay parental anxiety, especially those who staying far from hospital.
  • 170.
    Prognosis Children whodevelopmentally normal at the time of febrile fits will continue to develop normally [ Nelson&Ellenberg, Verity et al]There was no difference in children between those experiencing simple seizures and complex seizures.
