Head Trauma and Parkinson's


Head trauma, particularly repetitive or severe injuries, has been linked to an increased risk of developing Parkinson's disease (PD) and other Neurodegenerative disorders.

 Key findings: 1. Traumatic brain injury (TBI) increases PD risk by 50-300% (varies depending on study). 2. Repeated head trauma (e.g., concussions) is more harmful than single incidents. 3. Risk is higher for injuries involving loss of consciousness or memory impairment. 4. Military veterans and contact sports athletes (e.g., boxing, football) show elevated PD risk.

 Possible mechanisms: 1. Damage to dopamine-producing neurons 2. Inflammation and oxidative stress 3. Accumulation of tau and amyloid proteins (associated with neurodegeneration) 4. Disrupted blood-brain barrier 

Symptoms and diagnosis: 1. PD symptoms may appear years or decades after head trauma. 2. Classic PD symptoms: tremors, rigidity, bradykinesia, postural instability. 3. Diagnosis requires medical evaluation, imaging, and ruling out other conditions.



Ocular Manifestations of PD may include impaired convergence (i.e. convergence insufficiency), decreased blinking frequency, dry eye, punctate epithelial erosions, blepharitis, blepharospasm, and apraxia of eyelid opening(Apraxia of lid opening (ALO) is a rare condition that makes it difficult to open the eyes voluntarily, even though the eyes can open and stay open at other times).


Studies and research: 1. National Football League (NFL) players study (2012): linked repeated head trauma to increased PD risk. 2. Veterans Administration study (2018): found TBI increased PD risk in military veterans. 3. Ongoing research explores biomarkers and potential therapeutic targets.

Regarding new research in PD detection, there are several promising areas of investigation:

  • Biomarkers: Researchers are exploring biomarkers, such as changes in specific proteins or genetic markers, that could be indicative of PD before symptoms appear.
  • Imaging Techniques: Advances in imaging technology, including deep brain stimulation (DBS) and functional MRI, are being used to study changes in the brain associated with PD.
  • Wearable Devices: Wearable devices that monitor movements and other physiological parameters may be able to detect early signs of PD.

Prevention and management: 1. Reduce head trauma risk through safety measures (e.g., helmets, seatbelts). 2. Monitor and manage concussions promptly. 3. Encourage healthy lifestyle choices (exercise, social engagement). 4. Consider cognitive training and mental stimulation. While head trauma is a risk factor, it is essential to note: 1. Not everyone with head trauma develops PD. 2. PD is a complex, multifactorial disease. If you or someone you know has experienced head trauma, consult a NEUROSURGEON for personalized guidance.

Cauda Equina Syndrome

Image
  Cauda Equina Syndrome (CES) is a serious medical condition requiring prompt attention. Definition Cauda Equina Syndrome occurs when the cauda equina nerves (lower spine) are compressed or damaged, disrupting communication between the brain and lower body. Causes 1. Herniated disc 2. Spinal stenosis 3. Trauma (fall, accident) 4. Infection (abscess, meningitis) 5. Tumor 6. Birth defects Symptoms 1. Severe low back pain 2. Pain, numbness, or tingling in legs 3. Weakness or paralysis in legs 4. Bladder and bowel dysfunction 5. Urinary retention or incontinence 6. Constipation 7. Sexual dysfunction Ocular Manifestations : Blurred vision can be an initial symptom of a schwannoma of the cauda equina, a rare nerve root problem that occurs when the nerves at the bottom of the spinal cord are compressed. Other ocular manifestations of conditions that can affect the cauda equina include: Neurosarcoidosis A multisystem disorder that can cause neurologic disease, including cranial n...

Epicanthic Folds and Hooded Eyelids, similarities and differences

Image
  Epicanthic folds are skin folds of the upper eyelid that cover the inner corner of the eye. There are four main types: - Epicanthus Supraciliaris: This type runs from the brow, curving downwards towards the Lacrimal sac. - Epicanthus Palpebralis: Beginning above the upper tarsus, it extends to the inferior orbital rim. - Epicanthus Tarsalis: Originating at the upper eyelid crease, it merges into the skin near the medial canthus. This type is most often found in East Asians. - Epicanthus Inversus: This type runs from the lower eyelid skin over the medial canthus and extends to the upper lid . These folds are more common in certain populations, including East Asians, Southeast Asians, Central Asians, North Asians, Polynesians, Micronesians, Indigenous peoples of the Americas, and some African people ¹. They can also be associated with various medical conditions, such as Down syndrome, Zellweger syndrome, and Noonan syndrome In terms of eye health, epicanthic folds may: - Decrea...
