The concept of “away from the midline” is closely associated with four key entities: the midline itself, laterality, the cerebral hemispheres, and the body’s motor control. The midline refers to an imaginary vertical line that divides the body into left and right halves. Laterality denotes which side of the body is dominant, whether left or right. The cerebral hemispheres are the two halves of the brain, with each controlling the corresponding side of the body. Lastly, the body’s motor control system regulates movements and relies on signals from both cerebral hemispheres. Understanding the relationship between these entities is essential for comprehending the concept of “away from the midline.”

Cognitive and Motor Deficits After Stroke: A Journey Through the Brain’s Aftermath
Strokes, those sneaky vessels bursting or blocking, can leave their mark not just on your physical abilities but also on your mental capabilities. And guess what? The side of your brain that takes the hit determines the type of trouble you’re in for!
-
Your Brain’s Side Hustle:
The left side of your brain is a multitasking master, handling speech, language, and logical thinking. If it’s the one that suffers a stroke, you might struggle with finding the right words or making sense of the world around you. -
Right Brain Revolution:
On the other hand, the right side of your brain is an artistic genius, responsible for spatial awareness, emotions, and creativity. A stroke here can lead to visual neglect, where you ignore one side of your surroundings like it’s invisible! -
Motor Mayhem:
Strokes can also mess with your movement abilities. Hemiplegia, the complete loss of movement, and hemiparesis, the partial loss, can make even the simplest tasks, like raising your hand, a challenge. And get this: where the stroke happens in the brain determines which side of your body will be affected!
Understanding the Enigmatic Phenomenon of Spatial Neglect: Unraveling the Mysterious World of Unilateral Disregard
Stroke, a life-altering event, can often leave its survivors grappling with a myriad of cognitive and motor challenges. Among these, spatial neglect emerges as a curious and often perplexing phenomenon, where individuals seem to be oblivious to one side of their world. In this blog post, we’ll venture into the fascinating realm of spatial neglect, exploring its characteristics, causes, and the intricate mechanisms underlying this intriguing condition.
Spatial neglect is a strange but very real condition that affects people who have had a stroke. It’s like wearing blinders that block out one side of your vision, except this time, it’s not your eyes that are doing the blocking, it’s your brain! People with spatial neglect often don’t notice things on one side of their body or in the space around them. It’s like their brains have decided to ignore that whole side of the world.
Types of Spatial Neglect
There are two main types of spatial neglect:
- Visual neglect: This type of neglect affects your vision. People with visual neglect may not be able to see things on one side of their body or in the space around them. They may bump into objects on that side or even ignore people standing there.
- Unilateral neglect: This type of neglect affects your awareness of one side of your body. People with unilateral neglect may not be able to move or feel things on one side of their body. They may even dress only one side of their body or eat only from one side of their plate.
Causes and Mechanisms of Spatial Neglect
The exact cause of spatial neglect is still not fully understood, but it’s thought to be related to damage to the right hemisphere of the brain, which is responsible for processing spatial information. This damage can disrupt the brain’s ability to create a coherent representation of the world around us, leading to the symptoms of neglect.
The Consequences of Spatial Neglect
Spatial neglect can have a significant impact on a person’s life. It can make it difficult to perform everyday tasks, such as eating, dressing, and walking. It can also lead to social isolation, as people with neglect may have difficulty interacting with others.
Treatment for Spatial Neglect
There is no cure for spatial neglect, but there are treatments that can help to improve symptoms. These treatments may include:
- Occupational therapy: This type of therapy can help people with neglect to relearn how to perform everyday tasks.
- Physical therapy: This type of therapy can help people with neglect to improve their balance and coordination.
- Speech therapy: This type of therapy can help people with neglect to improve their communication skills.
Mirror Movements and Mirror Syndrome: What Happens When Your Body Does a Double Take?
Have you ever wondered why, when you wave goodbye to a friend, you might unconsciously wave with your other hand too? Or why, when you scratch an itch on your left arm, your right arm might start twitching?
These are two common examples of mirror movements, an intriguing phenomenon that can sometimes occur after a stroke. In this blog, we’ll dive into the fascinating world of mirror movements and their more severe counterpart, mirror syndrome, exploring their causes, consequences, and what we can do about them.
What Are Mirror Movements and Mirror Syndrome?
Mirror movements are involuntary movements that occur when you move one side of your body and the corresponding opposite side moves as well. Think of it as an instant dance party that your body throws without your permission!
Mirror syndrome, on the other hand, is a more severe condition where the mirror movements become excessive and interfere with everyday activities. It can be like having a mischievous twin that insists on copying your every move, but without any coordination or rhythm.
How Do Mirror Movements Happen?
After a stroke, damage to certain areas of the brain can disrupt the normal pathways that control our movements. This can lead to a disconnection between the brain’s commands and the body’s response, resulting in these involuntary mirror movements.
The Impact of Mirror Movements
While mirror movements can be amusing at times, they can also affect your daily life. Simple tasks like buttoning a shirt or brushing your teeth can become frustrating if your other hand keeps getting in the way. Additionally, mirror movements can also reduce the effectiveness of physiotherapy, making it harder to regain normal movement.
Tackling Mirror Movements
The good news is that mirror movements can often improve over time as the brain gradually recovers from the stroke. However, there are also strategies you can try to **minim
