Considering the advancement in the current era, the concentration and presence of detrimental chemicals in the products we use during our day-to-day lives has escalated quickly. Overtime, these destructive chemical substances can severely impact the nervous system and cause neurological deficits. So here are top 5 chemicals that damage human brain!


It is commonly found in toothpaste fluoridated drinking water. This mineral has been proved to be beneficial, but excess use of this can be proved to be disastrous too. It has not only adverse effects on brain during early development, but it also lowers the IQ among young children. Fluoride can combine with Aluminium to form Aluminium fluoride, providing the harmful Aluminium an easy access through the blood-brain barrier. The presence of Aluminium have link with Alzheimer’s disease. Moreover, using fluoridated water doubles the risk of hypothyroidism. Gradual degeneration of brain parts such as hippocampus and cerebellum are also caused by fluoride, along with the impaired function of the pineal gland.


Heavy metals, especially lead and mercy, are highly toxic to both central and peripheral nervous systems. Exposure during intrauterine life can lead to adverse effects on the brain after birth. And after ingestion, inhalation or dermal exposure to mercury and lead compounds, individuals may suffer from neurological and behavioural disorders. They cause severe symptoms like tremors, insomnia, headaches, neuromuscular deficits and motor dysfunction. Even decreased intelligence in children and young adults is associated with lowest blood lead concentration.


The two classes of pesticides Organophosphate and Carbomate results in developmental toxicity. These chemical substances interfere with nerve signal in brain and spinal cord. Also can cause symptoms such as migraine, nausea, chest pain, diarrhea, confusion and muscular pain. In case of severe pesticides poisoning, there may be adverse effects as convulsion, breathing difficulty, coma and even death. In addition to this, organochlorine found in pesticides is nervous system stimulants which lead to tremors, hyper excitability and even seizures.


It is widely used in dry cleaning and textile industry. This chemical poses a risk to the brain’s health and can be severely hazardous. The behavioural changes, problems with co-ordination, dizziness, persistent headaches, fatigue and unconsciousness are the immediate effects of inhaling tetrachloroethylene. Chronic effects include detrimental effects on the sensory nervous system, memory, attention, reaction time and also cause colour vision defeats. Moreover, according to researchers, individuals who consistently inhale air contaminated with tetrachloroethylene have a much risk of developing brain tumor.


It is commonly used in cosmetic products and plastic ware. It adversely impact hippocampus, a region of the brain involved in memory and learning, particularly in young adults and growing children. This chemical is also responsible for the reduction of neurones and synapses in the brain tissues. According to some studies, both male and female rats exposed to phthalate faced a decrease in their preferential cortes and an overall deficit in cognitive flexibility. Considering significance of the central nervous system, it is indeed vital to stay conscious, while using products containing hazardous chemical substances.
