Terminal lucidity is a phenomenon where people with neurodegenerative diseases or those in a terminal state briefly regain mental clarity before dying. It is believed to occur due to chemical changes in the brain and usually lasts minutes to hours. This phenomenon is striking and has captivated the interest of human health professionals.

Beyond the complex moments that can happen before the death of a loved one, the truth is that we can appreciate people who show a lot of vitality. In this PsychologyFor article, we will provide you with information about What is terminal lucidity, why it happens and how long it lasts.

What is terminal lucidity

Terminal lucidity is a clinical phenomenon that consists of a mental clarity shortly before death. Neurodegenerative diseases, such as advanced dementia or Alzheimer’s, often occur in people. This episode may include recognizing family members, coherent communication, or vivid memories.

In the final stage of life, the brain activity can be altered temporarily and cognitive functions are restored. Furthermore, although it does not have a scientific basis, some people interpret terminal lucidity as a transcendental phenomenon or as a moment in which consciousness prepares for death.

Along the same lines, this clinical condition allows temporarily recover memories in the short term. For this reason, the person can maintain a logical and coherent conversation. However, doubts still persist regarding the person’s own lack of knowledge about their current state of health.

Terminal lucidity, although little understood, is a reminder of the complexity of the human brain and the emotional depth experienced in the final moments of life. In this article you will find more information about How the human brain works.

Why terminal lucidity happen

Terminal lucidity is an intriguing and poorly understood phenomenon from a clinical and psychological point of view. There are several theories that try to explain this phenomenon:

  • Neurobiological factors: Before death, there may be a temporary reorganization of brain networks that allows better communication between cognitive areas. This phenomenon could be related to a final release of neurotransmitters, such as dopamine or glutamate, that affect consciousness and perception.
  • Brain inflammation: Nerve tissues damaged by health problems become inflamed during the most critical stages. However, the brain presents a temporary improvement that allows the acquisition of social, cognitive, emotional and behavioral skills during the stage of terminal lucidity.
  • Psychological and emotional theories: From a psychological perspective, terminal lucidity could reflect a mechanism of emotional reconciliation or psychological closure. In this state, the brain prioritizes processes related to the resolution of internal conflicts. Thus, this phenomenon can provide the patient with a last opportunity to express unresolved thoughts or emotions, or to say goodbye.

  • Temporary improvement of communication skills: People with terminal lucidity speak more coherently and fluently, even if they previously had severe difficulties expressing themselves. Some manage to express deep thoughts or emotions that they could not before.
  • Increased awareness of the environment: People with terminal lucidity clearly recognize those around them, the place they are in or the context, which contrasts with their usual state of disorientation.
  • Expression of wishes or thoughts: Some patients take advantage of this time to make confessions, resolve family conflicts, or share important messages.
  • Brief apparent physical improvement: Although less common, some people may appear more alert or physically active, sitting up or performing movements that they could not do before. This physical improvement is generally temporary and does not indicate real recovery.
  • Reconnecting with lost memories or abilities: Sometimes, those who experience mental clarity can access memories that seemed forgotten or perform simple actions that were impossible before, such as smiling or holding the hand of a loved one.

How long does mental clarity last?

Terminal lucidity has a highly variable duration, but is generally brief. In most cases, this phenomenon lasts from a few minutes to a few hoursalthough sometimes it can last for a day or more.

It is important to note that this sudden improvement does not indicate real recovery of the disease, but rather it is a transitory episode that usually occurs in the hours or days before death. The duration will depend on factors such as the underlying disease, the patient’s general condition and the biological processes involved in the final stages of life.
