caffeine epilepsy seizures June 4, 2022

Abnormally immoderate or synchronous neuronal interest is what reasons the symptoms and symptoms and signs and symptoms of epileptic seizures. The seizure threshold is reduced with the aid of using reduced sleep, immoderate pressure or medicinal drugs with convulsant or threshold decreasing substances, in addition to caffeine.

Caffeine is metabolized with the aid of using cytochrome P450 1A2 and its over-saturation because of immoderate intake or inhibition of the enzyme can cause multiplied caffeine toxicity.

A mild intake of caffeine can set off CNS (crucial fearful device) and behavioural stimulations. These outcomes are mostly associated with the antagonism of adenosine receptors. Adenosine blocks the excitatory synaptic responses thru modulation of neurotransmitter launch and neuronal excitability with the aid of using the decreasing potassium-mediated launch of glutamate and aspartate.

Caffeine antagonizes the intoxicating outcomes of alcohol. Consequently, there was a dramatic international boom in the intake of caffeinated liquids collectively with alcohol, particularly among younger adults.

Effects of Caffeine and Taurine

Caffeine has a psychostimulant impact on the crucial fearful device with the aid of using antagonizing adenosine A1 and A2A receptors which might be located abundantly within the cerebral and cerebellar cortices, hippocampus and thalamic nuclei. Adenosine A1 receptor inhibits neurotransmitter launch with the aid of using controlling the calcium currents.

Its inhibitory impact is recommended to be more potent than that of all inhibitory neurotransmitters. The basal nuclei which might be the important motor inhibitory place within the mind exert its feature the usage of the adenosine 2A receptors with the aid of using lowering the affinity of dopamine to the D2 receptors. Adenosine 2A receptors also are placed in excitatory nerve terminals during the mind in which they manipulate synaptic plasticity processes. Caffeine’s antagonism of adenosine receptors favours hippocampal hyperexcitability within the shape of multiplied improvement of long-time period potentiation. Higher doses of caffeine (a hundred mg/kg or extra) initiate hippocampal hyperexcitability which is much like what’s recorded at some stage in generalized seizures.

The physiological outcomes of caffeine, on a molecular level, confirm its position in favouring a kingdom of arousal and neuronal hyperexcitability with the aid of using antagonizing the inhibitory outcomes of adenosine at those receptors and consequently precipitating a pro-epileptogenic kingdom.

In comparison to caffeine, taurine performs an inhibitory position within the crucial fearful device. Studies advocate that pretreatment with taurine had anticonvulsant outcomes of pilocarpine-triggered convulsions. This impact is probably mediated with the aid of using the discount of acetylcholine esterase (AChE) and nitric oxide (NO) tiers within the hippocampus.

Subcutaneous taurine had a giant impact in lowering the possibility and growing the latency of kainic acid triggered tonic-clonic seizures.


In conclusion, a low dose of caffeine is related to a pro-epileptic impact within the shape of a multiplied possibility and reduced latency time to seizures. In comparison, taurine intake appears to don’t have any fantastic impact on the equal seizure parameters. Considering those results, we consider that what stays to be addressed is the impact of better doses of caffeine in acute, persistent and withdrawal exposures on comparable and extra particular seizure parameters which include the form of seizures happening and mind electric interest at some stage in and after the seizure.
