Brief Summary:
This research is being done to observe the safety, tolerability, side effects, and effectiveness of the ketogenic diet in people with continuous seizures (status epilepticus) being treated in a neurointensive care unit.

Arm Intervention/treatment
Experimental: Ketogenic diet
Patients will receive the ketogenic diet as a formula delivered via feeding tube. Once able to tolerate food by mouth, patients will be switched to a modified Atkins diet.
Dietary Supplement: Ketogenic diet
4:1 ratio fat: carbohydrates and protein ketogenic liquid via enteral feed
Other Name: KetoCal 4:1 liquid

Primary Outcome Measures :
  1. Feasibility [ Time Frame: 2 weeks ]
    Whether or not the diet protocol was followed

Secondary Outcome Measures :
  1. Time to seizure reduction [ Time Frame: Participants will be followed for the duration of the hospital stay, an expected average of 6 weeks ]
    The time (in days) from initiation of the diet to > 50% reduction in frequency and to resolution of electrographic (based on continuous EEG findings) and/or clinical seizures will be recorded.

  2. Ranking of tolerability measures on a 10 point scale [ Time Frame: 6 months ]
    Participants will complete a scale ranking convenience, taste, texture, tolerance

  3. Number of participants with adverse events and description of events [ Time Frame: 6 months ]
    Reported side effects will be recorded as well as number of patients who develop side effects.

  4. Time to achieving serum and/or urinary ketosis [ Time Frame: Until serum or urinary ketosis is achieved, an expected average of 2 weeks ]
    The time (in days) from starting the ketogenic diet to achieving urinary and/or serum ketosis will be recorded.
