Brain adenosine triphosphate: decreased concentration precedes convulsions
Science (New York, N.Y.)
|July 10, 1970
Summary
Brain adenosine triphosphate (ATP) levels dropped before seizures in rats exposed to hypoxia or treated with convulsants. Boosting ATP production delayed seizure onset, suggesting a protective role.
Area of Science:
- Neuroscience
- Biochemistry
Background:
- Adenosine triphosphate (ATP) is the primary energy currency in cells.
- Seizures represent a state of excessive neuronal firing, demanding significant energy.
Purpose of the Study:
- To investigate the role of brain adenosine triphosphate (ATP) levels in the development of generalized convulsions.
- To determine if modulating ATP levels affects seizure susceptibility.
Main Methods:
- Measurements of brain adenosine triphosphate (ATP) concentration in unanesthetized rats.
- Induction of seizures using acute hypoxia, hydroxylamine, or pentylenetetrazole (Metrazol).
- Intervention to stimulate ATP production prior to or during seizure induction.
Main Results:
- Brain ATP concentration significantly decreased preceding generalized convulsions.
- ATP levels continued to decline as the seizure episode progressed.
- Stimulating ATP production effectively delayed the onset and progression of seizure activity.
Conclusions:
- A decrease in brain adenosine triphosphate (ATP) is closely associated with the onset and progression of generalized seizures.
- Maintaining or increasing brain ATP levels may serve as a neuroprotective mechanism against seizure activity.

01:20Desensitization and Tachyphylaxis
Tachyphylaxis is described as a rapid decrease in response to a drug after repeated or continuous administration of the same drug dose. It is a phenomenon where the body becomes less responsive to a particular substance or intervention over time, requiring higher doses or stronger interventions to achieve the same effect. It results from adaptive changes in the body's receptors, signaling pathways, or physiological processes that occur in response to prolonged exposure to a stimulus.

01:28Depolarizing Blockers: Mechanism of Action
Depolarizing blockers act on skeletal muscle fibers' membranes and induce their depolarization. Most depolarizing blockers have two quaternary N+ atoms that bind the nicotinic acetylcholine receptors and cause neuromuscular blockade within minutes.
Succinylcholine is the most commonly used depolarizing blocker. Chemically, it constitutes two molecules of acetylcholine joined together by an acetate methyl group. They act on the receptors in the same way as acetylcholine. Because succinylcholine...

01:19Depolarizing Blockers: Pharmocokinetics
Depolarizing blockers are administered through intravenous injection. Succinylcholine is the most common choice of depolarizing blockers in emergency clinical practices. Although they have a rapid onset, they readily diffuse away from the motor end plate into the extracellular fluid. They are metabolized by enzymes such as liver butyrylcholinesterase and plasma pseudocholinesterases. This produces a short duration of action, typically 5-10 minutes long, unlike nondepolarizing blockers, which...
01:18Antiepileptic Drugs: GABAergic Pathway Potentiators
γ-aminobutyric acid or GABA, plays a pivotal role as an inhibitory neurotransmitter in the brain. GABA pathway potentiators, also known as GABAergic drugs, are a class of pharmaceutical agents designed to enhance the functioning of the GABAergic system. These medications primarily treat epilepsy, a neurological disorder characterized by recurrent seizures.
The key GABA pathway potentiators used in epilepsy management are as follows.

01:14Antiepileptic Drugs: Glutamate Antagonists
Glutamate is a fundamental neurotransmitter in the central nervous system, playing a vital role in neuronal communication and various cognitive processes. Glutamate stands as the principal excitatory neurotransmitter in the brain. Its presence is crucial for the communication between neurons, underpinning essential processes such as synaptic transmission, neuronal excitability, and plasticity. These functions are vital for higher-order cognitive processes, including learning and memory. The...
01:20Seizures l: Introduction
Understanding seizures and epilepsy relies on key definitions that help in recognizing, classifying, and managing these disorders. These definitions provide a framework for recognizing, classifying, and managing seizure disorders.DefinitionsA seizure is a sudden, abnormal burst of electrical activity in the brain that can cause changes in awareness, movement, sensation, or behavior, depending on the area involved. Epilepsy is a chronic condition characterized by recurrent, unprovoked seizures,...
