[Irreversible brain death-Part 2. Spinalization phenomena]

Area of Science:

• Neurology
• Pathology

Background:

• Spinal automatisms, reflexes, and peripheral reactions are frequently observed in patients with irreversible brain death.
• These phenomena are often misinterpreted, leading to diagnostic challenges.

Purpose of the Study:

• To provide a comprehensive overview of the phenomenology of irreversible brain death.
• To discuss irreversible brain death from a neuropathological perspective.
• To differentiate irreversible brain death from pathological movements in comatose patients.

Main Methods:

• Literature review and synthesis of existing research on spinal automatisms and reflexes in brain death.
• Neuropathological analysis and case study review.
• Comparative analysis of motor reactions in brain death versus other disorders of consciousness.

Main Results:

• Spinal automatisms and reflexes are consistent findings in irreversible brain death.
• These reactions are compatible with and supportive of the diagnosis of brain death.
• Distinguishing these reactions from those seen in comatose states is crucial for accurate diagnosis.

Conclusions:

• Spinal automatisms and reflexes are not contradictory to brain death but rather supportive evidence.
• Understanding the neuropathological basis is key to accurate interpretation.
• Clear diagnostic criteria are essential to avoid misdiagnosis in patients with severe brain disorders.
