About uprightdoctor

I am a sixty year old retired chiropractor with considerable expertise in the unique designs of the human skull, spine and circulatory system of the brain due to upright posture, and their potential role in neurodegenerative diseases of the brain and cord. I have been writing about the subject for well over two decades now. My interests are in practical issues related to upright posture and human health.

Midbrain Atrophy in Parkinson’s, Alzheimer’s and Multiple Sclerosis

The midbrain is penetrated by the cerebral aqueduct of Sylvius and surrounded by cisterns that contain CSF. Blockage of CSF flow may play a role in enlargement of the cerebal aqueduct and atrophy of the midbrain in Alzheimer’s Parkinson’s and multiple sclerosis, as well as as signs of nystagmus and diplopia. Continue reading

Dissociation of CSF Flow in Neurodegenerative Diseases

Dissociation of CSF flow between the cranial vault and spinal canal may play a role in many neurodegenerative diseases associated with hydrocephalus in children and adults such as: Dandy-Walker Syndrome, Alzheimer’s, Parkinson’s, multisystem atrophy, and multipe sclerosis. Continue reading

Hydrofracking, Ventriculomegaly and Brain Atrophy

Chronic venous drainage problems and high CSF pressure waves can lead to hydrofracking, ventriculomegaly and atrophy of the brain seen in neurodegenerative diseases, such as Alzheimer’s, Parkinson’s and multiple sclerosis. Continue reading

Ventriculomegaly and Mega Cisterns in Alzheimer’s, Parkinsons and MS

Poroelasticity of the brain plays a role in enlarged ventricles, called ventriculomegaly and shrinkage, called atrophy of structures that surround them causing many of the signs and symptoms seen in Alzheimer’s diseases, Parkinson’s disease and multiple sclerosis. Continue reading

Pulsatility, Pressure Waves and Neurodegenerative Diseases

Pulsatility and arterial pressure waves that are inadequately buffered in the brain may play a role in neurodegenerative diseases such as Alzheimer’s, Parkinson’s and multiple sclerosis. Continue reading

Blood, CSF and Battered Bones

The cranial vault and brain are poroelastic structures constantly battered by the pulsating waves of blood and CSF flow. The hydraulic force of CSF is strong enough to erode bone. It may similarly erode the brain. Continue reading

CSF and Cerebellar Symptoms in Alzheimer’s, Parkinson’s and MS

The cerebellum may be affected in Alzheimer’s disease, Parkinson’s disease, multiple sclerosis, Chiari malformations and Dandy-Walker syndrome due to obstruction of CSF flow in the foramen magnum and upper cervical spinal canal. Continue reading
