Status epilepticus with visual seizures in ketotic hyperglycemia

Area of Science:

• Neurology
• Metabolic Disorders
• Epilepsy

Background:

• Metabolic disturbances are linked to epileptic seizures, but the underlying mechanisms remain unclear.
• Ketone bodies typically offer protection against epilepsy, making seizures in ketotic states rare.
• Hyperglycemic seizures are usually partial, with visual seizures historically linked to occipital foci.

Purpose of the Study:

• To report a unique case of complex partial status epilepticus with visual seizures in a patient experiencing ketotic hyperglycemia.
• To investigate the relationship between metabolic disturbances, specifically ketotic hyperglycemia, and seizure activity.
• To explore the potential for long-term neuronal damage resulting from partial seizures.

Main Methods:

• Case study of a 48-year-old male patient.
• Clinical presentation with complex partial status epilepticus and visual seizures.
• Electroencephalogram (EEG) and Magnetic Resonance Imaging (MRI) for diagnosis and monitoring.

Main Results:

• The patient presented with complex partial status epilepticus and visual seizures associated with ketotic hyperglycemia.
• EEG indicated a temporal epileptogenic focus.
• MRI revealed alterations in the acute phase and at a 4-month follow-up, suggesting persistent neuronal changes.

Conclusions:

• This case highlights an unusual presentation of seizures in the context of ketotic hyperglycemia.
• It suggests that partial seizures, contrary to some previous reports, can lead to long-term neuronal damage.
• The findings underscore the complex interplay between metabolic states and neurological function in epilepsy.
