Brain health and how colour plays an important role in its maintenance are topics that are becoming more important as the world population ages and more people are exposed to chronic stress, poor dietary habits and traumatic injuries. While the exact colour of a healthy brain may vary from person to person and even between different regions of the brain, there is a general consensus among experts that a healthy brain should have a normal, uniform colour that is usually gray in shade.
The purpose of this article is to explore how brain colour and health are related, discuss the underlying causes of healthy brain colour, and look at the potential implications of an unhealthy-looking brain.
What is the Colour of a Normal, Healthy Brain?
The primary colour of a normal and healthy brain is gray. This consistency in colour is due to the fact that the brain is primarily composed of gray matter, which is made up of neurons and their interconnecting tracts. Additionally, the gray matter of the brain is surrounded by white matter, which is made up of axons, or nerve fibres, that interconnect different parts of the brain.
Both gray and white matter work together to ensure optimal communication and functioning of the brain. While the exact shades of gray may vary slightly from person to person or even between different brain regions, the overall colour of a healthy brain remains the same.
What Causes a Brain to Have an Unhealthy Colour?
A wide range of factors can lead to an unhealthy brain colour, from trauma to poor lifestyle choices. Traumatic brain injury is a leading cause of brain colour irregularities, and experienced a traumatic brain injury can result in brain colours that vary from person to person. Additionally, poor lifestyle choices – such as smoking, a lack of exercise, or an unhealthy diet – can also lead to an unhealthy brain colour.
The visible consequences of such lifestyle decisions can range from a yellowish-brown colour to a greyish-purple colour. Other more rare and serious diseases and disorders can also lead to abnormal brain colours.
Diseases such as Alzheimer’s and Huntington’s have both been linked to a dark brown colour in the brain, while a whiter colour than normal may be linked to a disease such as multiple sclerosis. Regardless of the underlying cause, an unhealthy brain colour can be a sign of an underlying issue and should be monitored by a medical professional.
The Implications of an Unhealthy Brain Colour
An unhealthy brain colour can have a number of potential implications, ranging from physical issues to cognitive problems. Physically, an abnormal brain colour can interfere with the normal functioning of the brain, resulting in slower processing, delayed responses, and other physical signs of stress or fatigue. Additionally, an unhealthy brain colour may also be indicative of an underlying physiological issue, such as a traumatic brain injury or a degenerative disorder.
From a cognitive perspective, an unhealthy brain colour can indicate a poor memory, reduced concentration and attention span, difficulty learning new information, and decreased ability to problem solve. As such, a change in the colour of the brain can be a sign of an issue that should be addressed by a medical professional as soon as possible.
In conclusion, the colour of a healthy brain is usually gray in tone and uniform in colour. This consistency in colour is the result of the brain’s primary composition of gray and white matter, which work together to ensure optimal communication and functioning of the brain.
An unhealthy brain colour, however, can be the result of various underlying factors, from lifestyle choices to trauma to serious diseases. Visible differences in the colour of the brain can indicate an underlying issue and should be addressed as soon as possible. Ultimately, it is important to take note of subtle brain colour changes to ensure that the brain remains healthy and functioning properly.
