It is not necessary to have pathogens, breakdown or for anything to cross the blood brain barrier in order to cause neurodegenerative conditions. Inflammation and autoimmune reactions alone can cause damage by the chemicals they release.NZer1 wrote:...there has to be an entrance to the BBB for the issues to be symptomatic once there is infection load and immune system reaction/inflammation and that process enables the pathogen to spread by stealth means of replicating the DNA of the immune system and also any antibiotics...

...inflammation and scaring is a breeding ground for many pathogens that grow in volume over time and the symptoms appear at differing time frames depending on the body status and the bacterial load.
The effects of compressive neuropathy are well understood. The cause of neurological symptoms, such as cranial nerves signs as well as brain atrophy in non-communicating childhood hydrocephalus is primarily due to abnormal shear forces and compression. The problem is corrected by increasing the drainage capacity with an internal or external shunt. Hydrocephalus in adults due to Chiari malformations and tumors cause similar neurological signs and symptoms due to shear forces and compression. Traumatic brain injuries likewise cause mechanical strains such as compression and shear forces due to the brain shifting inside the skull, as well as violent inversion flows that can damage nerves. They also cause swelling from edema which causes compression problems similar to hydrocephalus. Strokes cause cell death and neurodegenerative conditions due to a disruption in blood flow. It also sets off an ischemic cascade that releases destructive chemcials into the brain that are not pathogens. Ischemica atrophy is a major cause of Alzheimer's. My theory is that chronic ischemia, edema and hydrocephalus can cause neurodegenerative conditions.
There is a huge amount of knowledge in radiology, neurology and orthopedics to support the connection between trauma, misalignments of the spine and nerve injuries. In addition to traumatic brain injuries, the impact of macro strain types of misalignments of the spine, such as fractures, dislocations, scoliosis, spondylosis and lateral and central stenosis are well understood. They are primarlly due to compression. The compressive impact of Chiari malformations are also well known. The signs and symptoms all correlate clearly with the patients history, exam findings and images.
