According to me they are living as they being unconscious their metabolic activities are continuing.

Introduction:
When discussing patients who never come back to normal life, it is essential to differentiate between living and non-living organisms. In this context, the term "normal life" refers to the ability to function independently and engage in activities typically associated with human existence.

Living organisms:
Living organisms are characterized by various attributes, including the ability to grow, reproduce, respond to stimuli, and maintain homeostasis. These organisms possess a complex cellular structure and are capable of metabolic processes. It is important to note that living organisms, such as humans, have consciousness and can experience subjective experiences.

Patients who never come back to normal life:
When patients experience severe medical conditions or injuries that permanently impair their physical, cognitive, or psychological abilities, they may not be able to return to what was considered normal life before the incident. These patients may require constant medical assistance, have limited or no mobility, or exhibit cognitive or psychological impairments.

Living patients:
Patients who never come back to normal life but are still alive are considered living organisms. Although their abilities and quality of life may be significantly compromised, they maintain the fundamental characteristics of living organisms. They require ongoing medical care and support to sustain their existence.

Non-living patients:
The term "non-living" typically refers to inanimate objects or entities that do not possess the attributes of living organisms. Therefore, it is not appropriate to classify patients as non-living, even if they never regain their normal life.

Conclusion:
Patients who never return to normal life, despite receiving medical treatment, are still considered living organisms. While their abilities may be significantly impaired, they maintain the fundamental characteristics of living organisms. It is crucial to provide appropriate care and support to enhance their quality of life and ensure their well-being.
