Some of the tests require oral answers, while others use a pencil and paper. This evaluation may range from about 45 minutes to several hours.
In some people with PD, the cognitive changes are mild. In others, however, cognitive deficits may become more severe and impact daily functioning. Attention and working memory, executive function, and visuospatial function are the most frequently affected cognitive domains in PD. They may or may not be noticeable to the person.
They may or may not affect work or activities, depending on the demands of specific tasks and work situations.

Dementia refers to a syndrome in which patients have problems in more than one cognitive domain, and the cognitive problems significantly impair everyday life functioning. Besides PD, there are other important causes of cognitive dysfunction to keep in mind. Medical illnesses such as thyroid disease or vitamin B12deficiency can cause cognitive symptoms. Urinary tract infections or pneumonia can acutely cause confusion or hallucinations. In these settings, the cognitive symptoms are generally reversible after the infection or medical condition is treated. In addition, hearing loss or vision impairment can be a cause of cognitive problems.
If one cannot adequately see or hear the information well enough to process it, it can be difficult to learn, remember, and retrieve it. Cognitive function also can be affected by poor nighttime sleep and excessive daytime sleepiness.

Astrocytes and similar cells form tissue that surrounds and protects other nerve cells found within the brain and spinal cord. Connections from AIP to the pars opercularis travel anteroinferiorly to end at 43 and 6r.
Depression and anxiety may mimic cognitive symptoms. Besides dopamine, the neurochemical signals or neurotransmitters — acetylcholine, serotonin, and norepinephrine — are especially important for cognition, memory, attention, and mood. In autopsy studies, Lewy bodies, abnormal protein accumulations, have been found in neurons in brain regions responsible for cognitive processes.
For example, if cognitive problems develop abruptly, the physician may first search for an infection, new neurological problem such as a stroke , or newly prescribed medication. If the cognitive problems gradually develop, the evaluation may be different, and examination by a neurologist, neuropsychologist, or specialist in cognition may be helpful.
The medications work on the cholinergic system in the brain a neurochemical involved in attention and memory. Medications in this group include donepezil Aricept , rivastigmine Exelon , and galantamine Razadyne. Side effects include nausea, diarrhea, and in some, worsened tremor. The goals of these strategies are to help patients with cognitive tasks, communication, and daily activities; improve quality of life, and address safety concerns. Pill reminders, clock alarms, and timers are useful ways to help patients remember to take their medications.
Maintaining a regular routine for daily activities and exercise is important. Household items such as utensils, glasses, and keys should be kept in the same place all the time, and drawers can be labeled.
Patients may respond better when given choices, cues, or yes-no answers, particularly if wordfinding difficulties or slowed thinking is present. Mental activities can include doing puzzles, playing cards or other games, reading a book, going to lectures or concerts, or learning a new activity. These can be coupled with physical exercise such as learning new dance steps or yoga positions. Social interactions are an important piece of mental stimulation.
Many of these activities can be done with friends or family members. It is important for patients and caregivers alike not to get frustrated when cognitive problems, decreased initiation of activities, or communication problems are present. Patience is key. While it is not always an easy decision to stop driving, this is an important safety issue to address. The PL plays an important role in awareness and understanding the world on the opposite side of the body, which can manifest in different ways.
Sensory neglect — touch and temperature perception — is one of those. The PL has close connections with the occipital lobe, which controls vision.
That can present a big problem in therapy because patients may not pay much attention to one side of space during therapy and will need to be encouraged to pay attention to that side often during therapy. The ability to know where our body parts are in space is called proprioception. Malhotra points out that there is a variety of therapy for a proprioception deficit.
Malhotra addresses it with general, overall therapy, and she has had some success with aquatic therapy. Some PL stroke survivors can have involuntary movements of the arm. The dominant hemisphere PL plays a role in executive function, which involves the ability to think abstractly, see consequences and make decisions based on that analysis rather than in response to emotion.
This is mainly because of the connections between the PL and frontal lobe, which is the primary controller of executive functions. Neither doctor considered the PL stroke as causing emotional disturbances, primarily because it is not specifically related to the limbic system. However, Camargo pointed out that it can contribute to delirium. Not to recognize the left side of the world and losing all their sensory information that they usually receive from the opposite side of the body can be very confusing for these patients, which can be distressing and emotional.
Depression is common with PL stroke survivors, but no more, or less, common than survivors of strokes in other areas of the brain. We sometimes offer treatment, medical treatment as well as having neuropsychologists onboard who have sessions with our patients as well. In rehab, Malhotra, a physiatrist, prefers to use all three therapies — occupational, physical and speech — in working with PL stroke patients.
So, we try constraint-induced therapy. We have a zero-gravity machine that helps with ambulation. Contrast baths to help with sensation changes. Whatever works is how we feel in the rehab world. Like other lobes, the PL has the capacity for the unaffected side to take over some functions of the affected side.
That is the idea behind constraint-induced therapy. But when loss of sensation is your problem, it may not be that limiting because you can still move the arm or leg.
Therefore, you can do certain things, obviously not with the same dexterity as before, but it may be less limiting. I think those are really the key to optimal recovery.

Making the Best Decisions at Discharge After Stroke The type of rehabilitation and support systems a survivor receives at discharge can strongly influence health outcomes and recovery. What to Expect from Outpatient Rehab After stroke, about two-thirds of survivors receive some type of rehabilitation.
Outpatient therapy may consist of Several types of therapy. Whether a patient is referred to inpatient or outpatient therapy depends on the level of medical care required. What to Expect in Stroke Rehab Following a stroke, about two-thirds of survivors receive some type rehabilitation. In this second of our two-part series, we want to alleviate some of the mystery, fear and anxiety around the inpatient rehab part of the stroke recovery journey.
