What does non-focal mean in medical terms?

In contrast, a non-focal problem is NOT specific to a certain area of the brain. It may include a general loss of consciousness or emotional problem.

What are focal symptoms?

Focal neurologic signs also known as focal neurological deficits or focal CNS signs are impairments of nerve, spinal cord, or brain function that affects a specific region of the body, e.g. weakness in the left arm, the right leg, paresis, or plegia.

What is a non-focal neurologic exam?

non-focal findings on neurologic examination. These illnesses include many seizure disorders, narcolepsy, migraine and most other headache syndromes, the various causes of dizziness, and most types of dementia.

What does focal mean in neurology?

Neurological deficits - focal. A focal neurologic deficit is a problem with nerve, spinal cord, or brain function. It affects a specific location, such as the left side of the face, right arm, or even a small area such as the tongue. Speech, vision, and hearing problems are also considered focal neurological deficits.

What is focal weakness?

Focal weakness usually denotes asymmetry or predominance of upper versus lower extremities. Focality should alert the clinician to potential neurologic etiology, sometimes requiring urgent intervention. For the purposes of discussion, focal weakness here will include symmetric weakness.

What is a focal stroke?

Focal symptoms of stroke include the following: Weakness or paresis that may affect a single extremity, one half of the body, or all 4 extremities. Facial droop. Monocular or binocular blindness. Blurred vision or visual field deficits.

How does a neurologist check for nerve damage?

By measuring the electrical activity they are able to determine if there is nerve damage, the extent of the damage and potentially the cause of the damage. Frequently the neurologist will recommend common, noninvasive neurological evaluations such as electromyography (EMG) and nerve conduction velocity (NCV) testing.

How do nurses measure neurological status?

How do I document a neuro assessment nursing?

Documentation of a basic, normal neuro exam should look something along the lines of the following: The patient is alert and oriented to person, place, and time with normal speech. No motor deficits are noted, with muscle strength 5/5 bilaterally. Sensation is intact bilaterally.

What does focal mean in medical terms?

Pertaining to a focusFocal: Pertaining to a focus which in medicine may refer to: 1. The point at which rays converge as, for example, in the focal point. 2. A localized area of disease.

Is headache a focal neurological deficit?

In some disorders, headache is associated with focal neurological signs or symptoms. If this happens, one has to distinguish between a primary headache (eg, migraine) and a symptomatic headache secondary to an underlying infectious, inflammatory, vascular, neoplastic, or epileptic disorder.

What is a focal abnormality?

Focal slowing is the most common abnormality associated with focal lesions of any type, including (but not limited to) neoplastic, vascular, subdural collections, traumatic, and infectious (see images below).

What are headaches with focal neurological symptoms?

Migraine aura is defined as a focal neurological disturbance manifest as visual, sensory, or motor symptoms (Headache Classification Committee of the International Headache Society, 2004).

What is focal meningitis?

Focal neurologic signs include isolated cranial nerve abnormalities (principally of cranial nerves III, IV, VI, and VII), which are present in 10-20% of patients. These result from increased intracranial pressure (ICP) or the presence of exudates encasing the nerve roots.

What are Lateralizing signs?

Abstract. Clinical lateralizing signs are the phenomena which can unequivocally refer to the hemispheric onset of epileptic seizures. They can improve the localization of epileptogenic zone during presurgical evaluation, moreover, their presence can predict a success of surgical treatment.

Introduction

Patients with transient ischemic attack (TIA) are at high risks of ischemic stroke and coronary artery disease (CAD). Approximately 10% and 3% of patients with TIA develop ischemic stroke and CAD within 90 days, respectively.

Methods

The PROMISE-TIA (Prospective Multicenter Registry to Identify Subsequent Cardiovascular Events After Transient Ischemic Attack) was a nationwide prospective multicenter observational registration study, described in detail in elsewhere.

Results

Of the 1414 consecutive patients enrolled in this registry, 42 patients were excluded from this study because of TIA mimics, 8 patients of anxiety neurosis, 4 of convulsion, 4 of cervical spondylosis, 2 of peripheral neuropathy, 2 of migraine, 20 of others, and 2 of unknown.

Discussion

Among participants in the nationwide TIA registry, approximately one sixth had at least 1 nonfocal symptom. Hemiparesis was less likely; systolic blood pressure and ABCD2 score were lower in patients with TIA with nonfocal symptoms than in those without.

Summary

Patients with TIA with nonfocal symptoms were more likely to have DWI lesions and vascular lesions in the posterior circulation.

Acknowledgments

We acknowledge Prof Shigeharu Takagi from Tokai University, coinvestigator of the PROMISE-TIA study (Prospective Multicenter Registry to Identify Subsequent Cardiovascular Events After Transient Ischemic Attack), whose huge contribution ensured the success of the study and who passed away in 2017.

Sources of Funding

This study was supported, in part, by grants-in-aid (H21-Junkanki-Ippan-017 and H24-Junkanki-Ippan-011) from the Ministry of Health, Labour and Welfare of Japan. This study was not funded by any private company.

Epidemiology

Transient neurological attacks (TNAs) with focal symptoms are considered to be transient ischaemic attacks (TIAs) for which the management and prognosis is well understood. 2 However, non-focal TNAs with diffuse cerebral symptoms usually regarded as more benign in comparison to their counterpart and therefore management strategies vary.

Predicting Likelihood of TNAs

Oudeman et al. (2018) studied 67 patients with CAO and 62 patients without CAO, those with CAO were more likely to experience non-focal TNAs. 1 Interestingly, those with ≥1 non-focal TNA were more likely to have contralateral carotid disease or vertebral artery disease than those without CAO.

Diagnosing Non-Focal TNAs

The Rotterdam Study, a population based cohort study, demonstrated half of those with TNAs had presenting symptoms considered non-typical for a TIA (for example; disturbances of vision in one or both eyes consisting of flashes, gradual spread of sensory symptoms or coordination difficulties consisting of isolated disorder of swallowing or articulation, tingling of the limbs or lips, etc.).

Older Age and TNAs

In a 2013 UK based study of >65 year old adults, lifetime prevalence and incidence of all transient neurological symptoms (based on broad questions about speech, arm or leg weakness and sight issues) was substantially higher than the incidence of TIA from previous population-based studies.

Management Guidelines

The Royal College of Physicians (2016) National clinical guideline for stroke states “recurrent attacks of transient neurological symptoms despite optimal medical treatment, in whom an embolic source has been excluded, should be reassessed for an alternative neurological diagnosis”.

Prognostic Implications of TNAs

Data supports bilateral steno-occlusive disease potentiating haemodynamic compromise and therefore contributing to the prevalence of non-focal TNAs. 1 In those with bilateral carotid stenosis of >70%, aggressive blood pressure (BP) lowering has been discouraged.

Conclusion

Non-focal TNAs are common, in some instances difficult to discern from TIAs, and present a management conundrum that requires consideration of vascular risk factors including carotid disease status. Further research is needed (both mechanistic and epidemiological) to support a more informed management strategy for this patient group.
