Parkinsons disease is caused by low levels of a neuro-transmitter called dopamine in the brain, bipolar disorder is due to high levels of the same neurotransmitter. Lifetime Stock

Parkinsons disease and bipolar disorders are two ends of the same spectrum. Whereas, Parkinsons disease (PD) is caused by low levels of a neuro-transmitter called dopamine in the brain, bipolar disorder (BD) is due to high levels of the same neurotransmitter.

IANSlife spoke with Dr Madhuri Behari, Professor & Head, Department of Neurology, Fortis Hospital, Vasant Kunj, to find out what the relationship between the two is.


Dr Behari explains that Dopamine is essential for refined motor activities and all symptoms of Parkinson’s disease like tremour, slowness of actions, stiffness of muscles and postural stability are due to decreased levels of dopamine. Dopamine is also known as the happiness hormone and its decreased levels result in depression.

On the other hand, high levels of Dopamine causes symptoms of bipolar state such as manic behaviour (over-activity, not able to sleep, talkativeness, unnecessarily happy, suspicious behaviour, thinking that everyone is talking about them etc.), hallucination and other symptoms.

In India, there is very low awareness about these diseases and because of that there are lots of misunderstandings. The time patient reaches a neurologist the golden time is lost and in most of the cases we become helpless. While Parkinson’s disease is disease of elderly, Bipolar disorder usually occurs in young people. Since, the urban elderly population is living alone, it becomes difficult to track their behaviour for early symptoms of PD or bipolar symptoms due to side effects of high doses of levodopa (medicine given for PD).

It is also noted that in later stages of PD, when the dose of Levodopa or other drugs given to treat PD in high doses as per need of patient, some susceptible people develop mania,

hallucination and psychosis which can be treated by decreasing the dose of medicines and in some cases by doing deep brain stimulation operation. Whereas bipolar disorder can be treated by medicines only. It is highly recommended that we must pay close attention to elderly people to note occurrence of early symptoms of PD or bipolar symptoms.

Our mind is a machine which realizes that after 40 years of age there is nothing to learn and became stagnant. Constant absence of new learning may lead reduction in levels of certain neurotransmitters, hence it is recommended that we must start learning new brain activities after 40 years of age like learning new language, new hobby etc. to prevent loss of brain functioning or development of memory loss or dementia.

Brain is the most important part of our body which is complex and needs constant activation. While we can exercise our arms, legs, body or neck; similarly brain also needs regular exercise. (IANS)

Bangladesh over the years show that the state has failed in its duty to protect minorities

If humanity is hurt, God is hurt.

Religion without compassion might give way to hatred. Compassion with a "self-interest" motive is completely irreligious. But of late, some of the religions have departed from those basic human values. Love and compassion are for only those who follow their "specific" faith. Very sadly, the religions are up as trading commodities in the world of proselytization. Better preachers attract more followers. Of course, no issue if they are not vying for their religious "supremacy". But the ground reality is utterly different. The claim for exclusive supremacy has become the first commandment --- a real bone of contention among the existing religions. In the name of religion, we have polluted our minds. we have corrupted our souls. We have also gone so much astray that God must have now shut his gateway to heaven!

Taking out time for family has become very difficult as people are pretty busy in daily life and find very little time to spend with their loved ones. Planning a family vacation is an excellent way through which the whole family can step away from their daily life and have fun. You can find many destinations for a family vacation, but there is no place that can beat Aruba.

Milky Way galaxy as seen from Chitkul Valley

NASA's Chandra X-ray Observatory has for the first time spotted signs of a planet transiting a star outside of the Milky Way galaxy, opening up a new avenue to search for exoplanets at greater distances than ever before.

The possible exoplanet -- or planets outside of our Solar System -- candidate is located in the spiral galaxy Messier 51 (M51), also called the Whirlpool Galaxy because of its distinctive profile, NASA said in a statement.

Astronomers have, so far, found all other known exoplanets and exoplanet candidates in the Milky Way galaxy, almost all of them less than about 3,000 light-years from Earth.

An exoplanet in M51 would be about 28 million light-years away, meaning it would be thousands of times farther away than those in the Milky Way, NASA said.

"We are trying to open up a whole new arena for finding other worlds by searching for planet candidates at X-ray wavelengths, a strategy that makes it possible to discover them in other galaxies," said Rosanne Di Stefano of the Center for Astrophysics at Harvard and Smithsonian (CfA) in Cambridge, Massachusetts, who led the study.

The findings are published in the journal Nature Astronomy.

The exoplanet candidate was spotted in a binary system called M51-ULS-1, located in M51. This binary system contains a black hole or neutron star orbiting a companion star with a mass about 20 times that of the Sun. The X-ray transit they found using Chandra data lasted about three hours, during which the X-ray emission decreased to zero.

Based on this and other information, the team estimates the exoplanet candidate in M51-ULS-1 would be roughly the size of Saturn and orbit the neutron star or black hole at about twice the distance of Saturn from the Sun.

The team looked for X-ray transits in three galaxies beyond the Milky Way galaxy, using both Chandra and the European Space Agency's XMM-Newton. Their search covered 55 systems in M51, 64 systems in Messier 101 (the "Pinwheel" galaxy), and 119 systems in Messier 104 (the "Sombrero" galaxy).

However, more data would be needed to verify the interpretation as an extragalactic exoplanet. One challenge is that the planet candidate's large orbit means it would not cross in front of its binary partner again for about 70 years, thwarting any attempts for a confirming observation for decades, NASA said.

Named in honor of the late Indian-American Nobel laureate, Subrahmanyan Chandrasekhar, the Chandra X-ray Observatory is the world's most powerful X-ray telescope. It has eight times greater resolution and is able to detect sources more than 20-times fainter than any previous X-ray telescope.

Known to the world as Chandra (which means "moon" or "luminous" in Sanskrit), Chandrasekhar was widely regarded as one of the foremost astrophysicists of the twentieth century. (IANS/JB)
