CONCEPTS & GLOSSARY

  • Attack

  • Convulsion

  • Seizure

  • Fit


Attack

Attack

  • A violent act starting on with vigor


Seizures e pileptic n on epileptic what is that

Attack

  • Is used

  • to describe

  • epileptic &

  • non-epileptic

  • disorder.


Attack1

Attack

  • Is used

  • to describe

  • epileptic &

  • non-epileptic

  • disorder.


Attack2

attack

  • Is used

  • to describe

  • epileptic &

  • non-

  • epileptic

  • disorder.

  • We say:

    • Attack of laughing

    • Breath Holding Attack / or spell

    • An attack of febrile convulsion

    • Conversion Reaction

    • Epileptic attack


Attack3

attack

  • ?

  • Is used

  • to describe

  • epileptic &

  • non-

  • epileptic

  • disorder.


Attack4

attack

  • ?

  • Is used

  • to describe

  • epileptic &

  • non-

  • epileptic

  • disorder.


Convulsion

convulsion

An intense, paroxysmal, involuntary contraction

or series of contractions of

voluntary muscles


Convulsion1

convulsion

  • Is used to

  • describe

  • epileptic &

  • non-

  • epileptic

  • motor act /

  • shaking


Convulsion2

convulsion

  • Is used to

  • describe

  • epileptic &

  • non-

  • epileptic

  • motor act /

  • shaking


Convulsion3

convulsion

If there is no movement

(displacement in place), the term “convulsion” is not applied.

The term “convulsion” implies movement/s


Convulsion4

convulsion

  • We say:

    • Clonic convulsion but not tonic convulsions

    • Tonic-clonic convulsions

    • Myoclonic convulsion but not absence

    • convulsion.

  • ……Absence / Petit male is not a convulsion

    • Neither arrhythmia nor tachycardia nor apnea


Seizure

seizure

  • A sudden, involuntary event/s that may include:

    • Motor activity

    •  Altered level of consciousness

    • Somatosensory symptoms


Seizure1

seizure

  • Used to describe epileptic disorders


Seizure vs convulsion

Seizure vsConvulsion

  • A convulsive attack:

    • Always labeled as seizure

    • Contrary, not all seizures convulse

  • So a seizure is not synonym to convulsion

  • We say

    • Epileptic seizure/s.

    • Grand male seizure/s.

    • Petit male seizure/s.

    • His absence seizures are completely controlled by Valproic acid

    definition of epilepsy

    A chronicclinical condition defined as

    2 or more seizures

    resulting from

    hypersynchronous electrical discharge of a population of neurons and not secondary to specific provocation factor such as fever, infection, electrolyte imbalances or trauma


    Seizures e pileptic n on epileptic what is that

    Pathophysiology of

    epilepsy

    Epilepsy

    Abnormal, hypersynchronous electrical

    activation of a population of neurons in the cerebral cortex, either in:

    • Localized area

    • Focal //Partial seizure

    • Multiple areas

    • Generalized seizure

    Any perturbation that interferes with the synthesis, release, re-uptake or metabolism of these neurotransmitters may result in the occurrence of a seizure.

    Pathophysiology of

    epilepsy

    • Many pharmacologic therapies for seizures act upon these neurotransmitters

    • Increase

    • Inhibition

    • Decrease

    • Excitation


    Seizures e pileptic n on epileptic what is that

    Pathophysiology of

    epilepsy

    Controversy exists regarding the duration of seizure necessary to cause neuronal cell injury.

    Most, brief seizures, do not cause brain damage.

    Classification of epilepsy according to extension

    Classification of Epilepsy(According to Extension)

    By means of:

    • Clinical presentation

    • Electrical Guidance (EEG)


    Status epilepticus

    Status Epilepticus

    • A continuous seizure activity lasting

      >30minutes,

      or

    • The occurrence of ≥ 2 seizures in quick succession without return to usual level of consciousness

    An emergencyneurologic sequelae or death iftreatment is delayed


    Seizure presentation on arrival at the er

    Seizure Presentation On arrival at the ER

    • On active seizure

      • Shaking, deviation of eyes, frothy secretions,….

      • Staring

      • Breath holding (apneic) with cyanosis

  • Early post-ictal

    • Drowsy, in deep sleep, paralytic (odd),………

  • Late post-Ictal

    • Free of any manifestation (conscious alert ……..the attack is past).


  • Seizure presentation on arrival at the er1

    Seizure PresentationOn arrival at the ER

    • 1st attack

    • Previous attacks (1, 2 or more)

    • Under treatment with AED (withdrawal)

    • Never been treated with AED

    •  fever


    Seizure presentation on arrival at the er2

    Seizure PresentationOn arrival at the ER

    • The minority

    • New onset,non-febrile seizure

    The Majority

    Febrile convulsion

    or

    Aknown previous seizures

    A very small %

    Status epilepticus

    Most not seizing upon arrival in the casualty department


    Prognosis expectations

    Prognosis / expectations

    • The majority of pediatric seizures are single events without neurologic sequelae and most recurrent seizures can be controlled with medications.

    • Occasionally, however, seizures can be life-threatening (status epilepticus)


    Febrile convulsions

    Febrile Convulsions


    Incidence of epilepsy

    Incidence of Epilepsy

    • More common in children than adults

    • 1styr. of life / Highest incidence


    Incidence of epilepsy1

    Incidence of Epilepsy

    • About 3-5% of children will have at least one seizure by the age of 5 yr.:

      • >50% Benign febrile seizures.

      • 15% acute provoked seizure:

        • The leading cause:

          • Children under 5yr. /CNS infection

          • Adolescents / Head trauma

      • 10% Single unprovoked seizure and will never have another seizure

      • The remaining 25% Recurrent seizures or epilepsy


    Incidence of epilepsy2

    Incidence of Epilepsy

    • ¾ …… Idiopathic, with no known cause

    • ¼ ……Identifiable brain pathologyor

      underlying metabolic disorders.

    • A family history of epilepsy in 1st-degree relatives was found in 46.6% of patients.


    Seizure work up

    Seizure work-up

    To R/O conditions mimic seizures

    • The exact nature of the seizure:

      • Does the child have a known seizure disorder?

      • If this is the child’s 1st seizure, was the seizure febrile or non-febrile?

      • Was the seizure partial, generalized, or partial with secondary generalization?

      • Was the seizure provoked or unprovoked?
