• Misophonia:
Is a disorder characterized by intense, automatic fight-or-flight emotional and physical reactions (anger, disgust, panic) to specific, often quiet, repetitive sounds, most commonly chewing, breathing, or tapping. It is a neurological, brain-based condition, not a hearing issue, often beginning in childhood.
Brain studies show that in people with misophonia, the anterior insular cortex (AIC), which processes emotions and bodily sensations becomes hyperactive when hearing trigger sounds, interpreting them as direct threats.
There is an abnormal, intense connection between the brain's auditory system and the amygdala (the danger-detection alarm system).

Factitious disorder:
Or Munchausen syndrome,
Is a serious mental health and emotional condition in which people deceive others by pretending to be sick. They do this by faking symptoms, getting sick on purpose or hurting themselves. Factitious disorder also can happen when family members or caregivers falsely present others, such as children, as being ill, hurt or having a hard time functioning.
The primary drive is to assume the sick role and gain sympathy and attention, rather than tangible benefits like money or skipping work.
The Treatment is difficult because the person often denies the condition. It involves psychotherapy, such as cognitive-behavioral therapy (CBT), to manage the emotional issues driving the behaviour.

Reduced blood flow to the brain is thought to be a key factor in many forms of dementia, including Alzheimer's, and scientists have just identified a new mechanism regulating this flow, which may also help explain how it goes wrong.

• Huntington's disease (HD):
Is a fatal, inherited neurodegenerative disorder that causes progressive breakdown of nerve cells in the brain, typically presents as a triad of progressive psychiatric, cognitive, and motor symptoms. The earliest symptoms are often subtle problems with mood or mental/psychiatric abilities, which precede the motor symptoms for many people. Usually appearing in a person's 30s or 40s, symptoms include involuntary "dance-like" movements (chorea), cognitive decline, and psychiatric issues. While no cure exists, treatments manage symptom.

However, it can worsen anxiety, trigger sleep disruption, heartburn, GERD and cause digestive distress in those with Irritable Bowel Syndrome (IBS), temporarily raise blood pressure and heart rate. It may cause or exacerbate irregular heartbeats or heart palpitations.

أكو جانب من الأبحاث يربط الضغط النفسي والتوتر، الاكتئاب والمشاعر السيئة كلها بما يسمى شيخوخة الخلايا cell aging
وهذا عن طريق تقصير الجزء النهائي بالكروموسومات الّي يحميها ويحمي المعلومات الجينية وهالأجزاء تكون مثل ال cap للكروموسومات اسمها Telomeres
التيلوميرات بطبيعة الحال بكل انقسام خلية تقصر وهذا طبيعي ويفسر عملية الشيخوخة وحتى الأمراض المتعلقة بيها، لكن من تكون جداً قصيرة وقصرها متسارع بهالحالة راح تتعلق بالشيخوخة المبكرة والأمراض أيضاً
شنو الّي يأثر عليها ويخليها تقصر؟
• الضغط النفسي المزمن، بكل أنواعه
• هورمونات الضغط stress hormones الي تشمل الكورتزول، عن طريق تدمير الخلايا وزيادة الضغط التأكسدي oxidative stress والالتهاب
• المشاعر السلبية، بكل أنواعها حتى لو ماكو خطر أو تهديد حقيقي
• الصدمة، وخصوصاً لايف ستايل الطفولة
على العكس من ذلك، المشاعر الإيجابية الها دور حمائي، وتحمي التيلوميرات.
اليقظة الذهنية، التأمل، المرونة العاطفية، الترابط الاجتماعي الجيد والصحي، كل هالأمور مفيدة مو فقط على الصحة النفسية، بل حتى الصحة الجسدية عن طريق تبطيئ تقصير التيلوميرات، تقليل الجهد والضغط، والالتهابات.

Why neurology is beautiful? - perhaps There is no organ more central to human experience than the brain. It governs thoughts, emotions, memories, and our very sense of self. The study of how the brain controls every aspect of human existence is not only fascinating…
In the quiet corridors of medicine, no speciality stands closer to mystery than Neurology. Other branches of medicine often deal with organs that can be seen, touched, repaired, or replaced. The heart can be bypassed, the lungs ventilated, the kidneys filtered by machines. Yet the brain remains different—silent, hidden, and profoundly elusive. It is the only organ attempting to understand itself.
Neurology is not merely the study of disease; it is the study of consciousness, memory, thought, identity, emotion, and perception. A neurologist may explain where a lesion lies, identify which pathway has failed, or describe the electrical storm behind a seizure, yet still remain unable to answer the deeper question: why did it begin? Diseases such as Alzheimer's Disease, Parkinson's Disease, and Multiple Sclerosis continue to challenge modern science despite decades of research and astonishing technological progress. The more humanity uncovers about the nervous system, the more vast the unknown appears.
There is something almost philosophical about neurology. A damaged liver may alter chemistry, but a damaged brain can alter reality itself. A single microscopic lesion may erase a lifetime of memories, change a personality, or imprison a conscious mind within an unresponsive body. Within a network of fragile neurons lives every dream, fear, belief, and fragment of human existence. To study neurology is to stand at the border between biology and the soul.
And perhaps that is why neurology feels less like a completed science and more like an unfinished universe. Every answer opens the door to deeper questions, and every discovery reveals another layer of darkness waiting to be understood. The brain is not simply an organ inside the human body; it is the very thing that allows humanity to wonder about itself..

❲تَجرُبَة إدنجتون❳
هيَ واحدة من أشهر التَّجارُب عَلَىٰ الإطلاق.
كانت تجربة إدنجتون اختباراً رصديَّاً للنّسبيَّة العامّة، نظّمه الفلكيَّان البريطانيَّان آرثر ستانلي إدنجتون وفرانك واتسون دايسون عام 1919.
كانت الملاحظات عن الكسوف الكُلّي للشَّمس قد نفَّذتها بعثتان، واحدة إلىٰ جزيرة برينسيبي في غرب أفريقيا، والأخرىٰ إلىٰ مدينة سوبرال البرازيليَّة.
كان الهدف من الرحلات الاستكشافيَّة هو قياس انحراف الجاذبيَّة لضوء النُّجُوم الذي يمِر بالقرب من الشمس.
تنبأ ألبرت آينشتاين بقيمة هٰذا الانحراف في 1911؛ ولٰكن تبيَّن أنَّ هذا التّنبُّؤ الأوَّليّ غيرُ صحيح؛ لأنّه استند إلىٰ نظرية غير مكتملة للنّسبية العامَّة. حَسَّنَ آينشتاين تنبُّأه لاحقاً بعدَ الانتهاء من نظريته في 1915 والحصول على حلٍّ لمعادلاته من قبل كارل شوارزشيلد.
بعد عودة البعثات، قدَّم إدنجتون النّتائج إلىٰ الجمعيَّة الملكيَّة في لندن، وبعد بعض المداولات، تمَّ قبولها.
أدَّت التَّغطية الصّحفيَّة واسعة النَّطاق لنتائج هٰذه البعثات إلىٰ شُهْرة عالميَّة لآينشتاين ونظريَّاته.

كيف أثبت إدنجتون النّسبيَّة العامّة؟
عندما اختفىٰ ضوء الشَّمس في الكسوف، قاس إدنجتون مواقع النجوم البعيدة التي أصبحت مرئيَّةً في الخلفية.
أظهر أنَّه عندما يمرّ الضَّوء من تلك النُّجوم بالشَّمس، بدا أنّهم في مكان مختلف قليلاً مقارنةً بالّذي يكون عندما لم تكن الشمس هناك.
وهكذا أثبت أن الضَّوء يمكن أن ينحنيَ بوساطة الجاذبيَّة كما تنبَّأت النِّسبيَّة العامَّة.
استمرَّت جهود إدنجتون للتّحقق من النظرية النّسبيّة في عشرينيات القرن العشرين. من خلال كتاباته الشعبية وكتابه: النظرية الرٍياضيَّة للنِّسبيَّة (1923)، استحوذ إدنجتون على الخيال الفكري لجيله.

• Alice in Wonderland Syndrome (AIWS):
AKA Todd’s syndrome, is a rare neurological condition that temporarily distorts your perception of size, shape, time, and spatial relationships. Named after Lewis Carroll’s famous 1865 novel. It causes individuals to experience surreal, dream-like shifts in reality.
Objects may appear abnormally small (micropsia) or disproportionately large (macropsia), or they may seem further away or closer than they actually are. Body Image maybe altered, they frequently report that their own body parts feel like they are swelling, shrinking, or changing shape.
Time can feel like it is speeding up significantly or moving in extreme slow motion. Sounds may seem abnormally loud or intrusive, and the environment or people's faces may appear tilted or skewed
AIWS is not a single disease, but a symptom constellation linked to underlying conditions. It is most prevalent in children & young adults.
