Stranger Things

Stroke recovery is strange, something I’m sure any survivor would agree.  While the experience as a whole could be described as such, there are five neurological consequences of stroke that are stranger than most.

In the initial stages of my recovery, I was completely paralyzed on the left side of my body. The best way to describe the complete disconnection between mind and limb might have been as peculiar, if the experience itself had not been so overwhelmingly terrifying. In the early weeks of rehab, before I was even able to move my hand under my own volition, it began grabbing things like clusters of cables from surrounding medical equipment or objects such as pens from my bedside table. Done without intention, I was often completely unaware it had happened until I looked directly at it.

Alien Hand Syndrome occurs when stroke disrupts the brain’s normal communication between intention and movement, often involving the Corpus Callosum, which coordinates signals between the two hemispheres. The condition almost always affects the non dominant hand, typically the left, because it is controlled by the right hemisphere, which can still trigger movement even when it is no longer fully coordinated with the dominant hemisphere responsible for conscious planning. The result can be a hand that grasps objects, interferes with the other hand, or moves unexpectedly, leaving the person feeling as though the action was not initiated by them. In rare documented cases, patients have reported their hand repeatedly grabbing objects as it did with me, undoing actions performed by the other hand, or even rising toward their own throat, illustrating just how complex the brain’s systems for control and awareness truly are. As strange as Alien Hand Syndrome is - there are others.

Alice in Wonderland Syndrome is a rare neurological phenomenon where the brain temporarily distorts how a person perceives size, distance, or their own body. Objects may appear much smaller or much larger than they really are, rooms may feel stretched or compressed, and a person’s own hands or limbs can seem enormous or impossibly tiny. The condition is named after the strange size changes experienced by the character in Alice’s Adventures in Wonderland. It can occur after stroke when areas of the brain responsible for visual processing and spatial perception, particularly in the temporal or parietal regions, are disrupted.

One of the more unusual documented cases involved a patient who repeatedly experienced episodes where the entire room appeared to shrink while their own body seemed to grow larger and heavier. During these episodes, the person described feeling as though their arms and legs were expanding outward, filling the room while furniture appeared to recede into the distance. The sensation could last several minutes before suddenly returning to normal. Although deeply disorienting, these experiences are not hallucinations in the psychiatric sense. Instead, they are thought to occur when the brain briefly miscalculates visual and sensory information while trying to interpret the world around it.

Cotard’s Syndrome, sometimes referred to as “Walking Corpse Syndrome,” is a rare neurological and psychiatric condition in which a person believes they are dead, do not exist, or have lost internal organs or blood. The delusion can be so powerful that individuals may insist their body is decaying or that they are no longer alive in a literal sense. Although it is most often associated with severe depression or psychiatric illness, it has also been documented after neurological injuries, including stroke, when brain regions involved in self awareness, emotional processing, and reality perception are disrupted.

One well known case described a woman who became convinced she had died and no longer needed to eat because her body was already gone. She believed she was “empty inside” and that her organs had stopped functioning, even though medical tests showed otherwise. In some reports, patients have asked to be taken to a morgue or cemetery because they believe that is where they belong. These experiences highlight how profoundly the brain shapes our sense of existence. When certain networks are damaged, the brain’s ability to recognize the self as living and present can become deeply distorted.

Reduplicative Paramnesia is a rare neurological consequence in which a person becomes convinced that a place has been duplicated or exists in multiple locations at the same time. Someone might insist that the hospital they are in is actually located somewhere else, or that an identical copy of their home or town exists in another place. It most often occurs after damage to areas of the brain involved in memory and spatial orientation, particularly the right hemisphere and frontal lobes, which help the brain reconcile what we see with what we know to be true.

One well documented case involved a patient recovering in a hospital who repeatedly insisted that the building had been secretly moved to another city overnight. Despite being shown maps, windows, and explanations from staff, the patient remained convinced that the hospital was a perfect duplicate of the real one located somewhere else. The person could recognize the rooms, staff, and layout correctly, but their brain insisted the location itself had been copied. Cases like this demonstrate how stroke can disrupt the brain’s internal “map” of the world, creating a situation where memory and perception no longer agree about where a person actually is.

Prosopagnosia, often called Face Blindness, is a neurological condition in which a person loses the ability to recognize faces, even those of close family members or close friends. Vision itself remains normal, and the person can still see individual features such as eyes, hair, or a smile. The difficulty lies in the brain’s ability to assemble those features into a recognizable identity. This usually occurs when stroke affects the brain’s facial recognition centres in the temporal and occipital regions, areas that specialize in processing and remembering human faces.

In some documented cases, people with prosopagnosia have been unable to recognize their own reflection in a mirror or a photograph. Others have reported recognizing loved ones only by secondary clues such as voice, hairstyle, posture, or clothing. One patient described repeatedly walking past coworkers in the hallway because every face appeared unfamiliar until the person spoke. These experiences highlight how specialized the brain’s recognition systems are. When that network is disrupted, a face that should feel instantly familiar can suddenly become just another collection of features.

The Brain Is Stranger Than We Think

What these experiences reveal are both unsettling and fascinating: the brain is far more complex than we realize.

Stroke doesn’t just affect muscles or speech. It can disrupt the systems that control perception, emotion, identity, and even the sense of ownership over our own bodies.

Most survivors are prepared for the physical side of recovery. Far fewer are warned about the neurological surprises that can appear along the way.

But if something strange happens during recovery, it doesn’t mean you’re losing your mind.

You can find these and many others in our Post Stroke Effects Directory, which is currently being built. Please feel free to share your experiences with any of them, or with effects that may not yet be listed. Our goal is to create a resource built less around clinical explanations and more around shared survivor experiences.
