Asymmetrical Head Shape: Neurological Insights and Concerns - Neurology

Asymmetry of the brain?


I have had this symptom for a long time.
I noticed that in photos, the left side of my head appears particularly protruded.
I didn't pay much attention to it at first, but now I find it quite unattractive.
It feels soft to the touch, and it seems like there is fluid inside, but after researching, I don't think it is a symptom of hydrocephalus.
I've had this since childhood; it doesn't hurt, but when I touch the left side, it feels like I'm not directly touching my skull.
I have significantly more hair on the left side than on the right.
I'm wondering if this could be related.
Is there any way for this to improve?

Hello, it is not hydrocephalus; it should be a scalp issue.
I recommend seeing a dermatologist.

Understanding asymmetrical head shape can be a complex issue that intertwines various medical fields, including neurology, dermatology, and even psychology. Your description of the left side of your head feeling softer and appearing more prominent in photographs raises several important considerations.

Firstly, it’s essential to understand that head shape asymmetry can arise from a variety of factors, including genetic predispositions, developmental conditions, or even past injuries. In your case, since you mentioned that this has been a long-standing issue since childhood and that it does not cause pain, it may be more related to benign anatomical variations rather than a serious underlying condition. However, the sensation of "softness" and the perception of fluid could warrant further investigation.

One potential explanation for the asymmetry and the soft feeling could be related to the distribution of subcutaneous fat or the underlying bone structure. In some cases, individuals may have a more pronounced fat pad on one side of the head, which can create an illusion of asymmetry. Additionally, if there was any trauma to the skull during childhood, it could have led to uneven bone growth or healing, resulting in the current shape.

The concern about feeling like there is "water" inside your head is particularly interesting. While you have ruled out hydrocephalus (water on the brain), it’s important to note that the brain and surrounding tissues can have variations in fluid dynamics. Conditions such as benign intracranial hypertension or other cerebrospinal fluid (CSF) dynamics could potentially lead to sensations of fullness or pressure, although these are typically accompanied by other symptoms such as headaches or vision changes.

Regarding your question about whether the asymmetry can be "restored," it largely depends on the underlying cause. If the asymmetry is purely cosmetic and not associated with any functional impairment, surgical options such as craniofacial surgery could be considered, but these are typically reserved for more severe cases. Non-surgical options, such as physical therapy or craniosacral therapy, may help if there are muscular imbalances contributing to the appearance.

It’s also worth considering the psychological aspect of your concern. Body image issues can significantly affect self-esteem and mental health. If the asymmetry is causing you distress, discussing these feelings with a mental health professional could provide support and coping strategies.

In conclusion, while your asymmetrical head shape may not pose a medical threat, it is advisable to consult with a healthcare professional, such as a neurologist or a craniofacial specialist, to explore your concerns further. They can perform a thorough examination, possibly including imaging studies, to rule out any underlying conditions and provide you with tailored advice. Additionally, addressing any psychological impacts with a counselor or therapist can be beneficial in managing your feelings about your appearance.
