Appetite Brain Function
Depends on situation: Mental performance will be at its best when a person is well rested, well fed, not ill and in a comfortable setting. Sleep deprivation causes a predictable decline in performance. To this extent, naps that help one catch up with a sleep deficit will be helpful. Most mature adults can function well on 7-8 hours of sleep/24h. Performance in excess of capability is unlikely due to extra sleep. ...Read more
Hard to say...: Dopamine (DA) is not measured in clinical labs. It's extremely rapidly metabolized along a variety of pathways. Further, DA levels in blood bear little resemblance to DA activity in the brain - even less to the small brain regions and synapses where DA signaling is concentrated. Though DA *might* be relevant, the symptoms you describe could have a very large number of non-DA causes. ...Read more
No: The x ray radiation in a CT has no measurable or known effect on neural tissues. 1) dose is way too low and 2) nerves are relatively radioresistant since the cells don't reproduce very fast, if at all. There is a theoretical risk of cataracts and cancer years later, but this is incredibly small esp. for a single scan and controversial anyway. ...Read moreSee 1 more doctor answer
Do antipsychotics affect cognitive functions like memory processing speed word recollection executive functions? What's the best?
Cognitive effects: The newer antipsychotics (second-generation antipsychotics) theoretically are supposed to assist with improving cognitive impairments in various mental health conditions, such as schizophrenia and bipolar disorder.

Discuss your concerns with your doctor to make certain the goals you have are the same as your prescriber. Determining the cause of your symptoms is primary!

Do you have one?: Have you been diagnosed with a pituitary tumor? I suppose it's possible for a pituitary tumor to cause those symptoms, e.g. secondary hypothyroidism; but usually there are also physical symptoms. If you mean a BIG GROWING tumor, you shouldn't have that without also developing a bitemporal hemianopsia and walking into doorposts and walls. Why does this in particular worry you? ...Read moreSee 1 more doctor answer

Tissue Destruction: Alzheimrs disease is characterized by destruction of brain tissue in multiple brain areas. At first this is associated with simple forgetfullness, but in late stages people have loss of sphincter control, inability to bathe, dress and feed themselves. Under the microscope, the brains of alzheimer's patients show areas of tangled nerve cells. ...Read moreSee 1 more doctor answer
Not permanent: The side effects of Paxil, (paroxetine) as with many SSRI antidepressants can cause slower cognition, and loss of alertness and attention, however, these side effects should go away, or dissipate when the drug is stopped, with a few weeks. Since depression can also cause these symptoms, I would be careful blaming this on the drug if it hasn't been taken for at least 4-6 weeks regularly ...Read moreSee 1 more doctor answer
Absolutely!: The symptoms described are very typical of poor quality sleep. If a person has adequate time for sleep, but it is of poor quality, there may be an issue with sleep related breathing. If this is the case, a visit to someone trained in sleep disorders is needed. Even if the problem is lack of time for adequate sleep, better quality sleep can be obtained in less time with treatment. ...Read more
IT'S COMPLICATED: The mechanism of action of brain dopamine is not full understood. Low levels are associated with Parkinson's disease and probably ADHD and restless legs syndrome. Your symptoms may reflect depression and there are medications that can increase both brain dopamine and serotonin levels. Pounding heartbeat and tachycardia may be symptoms of panic disorder. You should get a psychiatric evaluation. ...Read moreSee 1 more doctor answer

Indirectly, yes: Visual loss in and of itself will not cause a loss of cognitive function. However, it may worsen the situation in people with dementia, as it impairs orientation and general functioning. So, a person with dementia and severe cataract may see an improvement in functioning if the vision is improved. ...Read more
Could MS located in the spine cause symptoms primarily impairing brain function? Like lightheadedness (brain fog) and bad short term memory?
Not related to MS: MS in the spine wouldn't cause any issues with brain function. MS taking place in the brain could cause some issues with lightheadedness but not memory issues, it would have to be a very end-stage degenerative MS to cause such symptoms and even then it would likely be a secondary cause, not a primary. Other things such as vertigo, viral infections, stress, sleep etc could be benign causes of this ...Read more
