Mercury Poisoning

Mercury poisoning refers to a toxicity due to consumption of mercury. This condition is largely linked to eating seafood, either due to consumption of certain types of mercury-containing fish or eating too much fish. 

Previously, it was possible to develop mercury poisoning if a mercury thermometer broke, which led schools in Singapore to phase it out from the labs.


Mercury poisoning is most notable for its neurological impacts. Anxiety, depression, memory problems and tremors are just a few of the many symptoms that can develop due to this condition. Mercury can also harm the kidneys and thyroid. 


Organic mercury compounds are able to reach high levels in the central nervous system, leading to neurotoxicity. Although the exact mechanism of how mercury induces neurological damage is unclear, it is able to disrupt cell cycle progression and induce apoptosis in several tissues. 


There is no known cure to mercury poisoning. The best way to treat it is to remove the source of mercury, by removing intake of seafood, or removing the source of mercury in the environment.

Parkinson's Disease

Parkinson’s disease is a progressive nervous system disorder that affects one’s movements. Parkinson’s disease signs and symptoms are different for every individual and may go unnoticed in the early stage. Symptoms typically start on one side of the body and remain worse on that side even after the symptoms begin appearing in both sides of the body.  Generally, the symptoms of Parkinson’s disease include tremors, slowed movement, rigid muscles, impaired posture and balance, loss of automatic movements such as blinking or swinging of arms when walking, and speech and writing changes.  Parkinson’s disease occurs when neurons in an area of the brain that controls movement becomes impaired or dies. These neurons normally produce dopamine. As more neurons become impaired or die, the amount of dopamine produced in the body is reduced significantly, causing the movement problems associated with Parkinson’s disease.  People with Parkinson’s also lose the nerve endings that produce norepinephri

Tinnitus

Tinnitus is a hearing condition often described as ringing in the ears. Tinnitus can also cause other types of noise in your ears such as: buzzing, roaring, clicking, hissing and humming.  The pitch heard from tinnitus can vary from a high squeal to a low roar, this can affect the patient’s ability to detect tinnitus from external sounds Tinnitus can develop gradually over time or occur suddenly. It is often associated with: age-related hearing loss, inner ear damage, earwax build-up and middle ear infection However, one in every three people with tinnitus doesn't have any obvious problem with their ears or hearing.

Pompe Disease

Pompe disease is a rare genetic condition where the body is unable to break down complex sugars. This is due to a deficiency in an enzyme called acid alfa glucosidase (GAA). Mutations in the GAA gene causes this disorder and results in a build up of glycogen in cells.  Pompe disease can appear in patients from within a few months of birth, at about 1 years old and even during the teenage years.  Those with Pompe disease usually inherit the disease from their parents. However, the allele for the disease is recessive, and may not be expressed in the parents. This disease is typically associated with weak muscles, poor muscle tone and an enlarged liver. However, there are many complications with regards to the respiratory system and motor skills which can also develop.  Enzyme replacement treatment is used for all Pompe patients. A drug called aglucosidase alfa is given intravenously, which acts as a replacement for GAA. Sources: https://my.clevelandclinic.org/health/diseases/15808-pompe-
