Corpora arenacea / brain sand of pineal gland


Brain sand or corpora arenacea
Definition:  The intercellular spaces of pineal gland contain calcified granular material known as brain sand or corpora arenacea

Locations of corpora arenacea:
Pineal gland
Brain sand also found in other brain area such as choroid plexus
In the leptomeninges,
In the habenular commissure

Composition:
  1. calcium phosphate,
  2. calcium carbonate,
  3. magnesium phosphate, and
  4. ammonium phosphate
How these calcifications are produce?
These calcifications are derived from precipitation of calcium phosphates and carbonates on carrier proteins that are released into the cytoplasm pinealocytes (the chief cells of pineal gland). These precipitation of calcium is release into intercellular spaced of pineal gland during secretion of pineal gland by exocytosis .
              They are the result of caclification of dead cells (e.g. erythrocytes or glial cells).

Factors increases the calcification :  
This calcification process is caused by constant exposure to substances like fluoride which build up in the body over time. Toothpaste, public water systems, hormones, food additives, excess sugar and sweeteners in your diet or even regular exposure to cell phones has been linked to the phenomenon of calcifying the pineal gland.
Clinical importance
It is appear as opaque structure in x-ray and located in the midline of the brain .
These concretions are conspicuous with imaging techniques and provide a useful landmark for orientation in the diagnosis of intracranial diseases.
Age changes :
 Calcification of the pineal gland is unfortunately typical in adults, and has been observed in children as young as 2 with estimates of 40% of population experiencing symptoms of heavy calcification of the pineal gland by the time they are 17. The degree of calcification was associated to various diseases.


Benefits of Decalcification
·         Improved Sleep & Mental Health 
·         Improved Immune System 
·         Weight Maintenance
·         Reduction in heart disease, diabetes and osteoporosis
·         Migraine Reduction 
·         Cancer Fighting
