I have had altered taste, at times, for years! In fact, I personally think that my taste being affected, where some foods just seemed to have a bland taste, whereas, most of my life, most always foods tasted good time after time, changed dramatically for me, about 12 years ago, when I was 68. Sure, I thought getting older can maybe affect taste! However, within a year of my having taste problems, I had freezing in place episodes, and falling down, where I sustained a concussion and 2 black eyes, with a severe headache! Even with imaging, and nerve conduction tests, at the small town, local hospital, it did not reveal to the local Family Doctor, what was wrong with me! So, the tests were deemed inconclusive! After another few episodes of my freezing in place, and falling, within the next month, my daughter, who has a nursing degree, decided to take me to the big city regional hospital, where a neurologist examined me, and declared that I probably had Parkinson’s Disease! With carb/levodopa tablets my symptoms improved, and other further testing, so it was confirmed that I have Parkinson’s Disease! Taste and smelling problems, were, for me, some first symptoms, of my having Parkinson’s Disease! My daughter moved us to the city where the regional medical center is located, about 10 years ago, and I’ve been seeing a neurologist ever since! Recently, I had an MRI, where the substantia nigra region of my brain ‘lit up’. In normal people the substantia nigra is dark! Parkinson’s Disease makes it ‘light’, where there is a loss of dopamine - is what my daughter explained to me! So, in my particular case, that explains why my taste is off! I do not have a salty, or sour taste problem, rather it’s like the food tastes bland, with not much flavor! My Grandma, as she got older, had that bland taste problem, too. Age can be a factor, or so I have been told by some medical professionals! The good news, though, is that I do not consistently have a taste problem! There are still many times when food still tastes real good to me, especially sweet food! Good luck as you discover what may be affecting your taste!
