Abstract
The diagnosis of multiple sclerosis (MS), despite well defined clinical criteria is not always simple. On many occasions it is difficult to differentiate MS from various non-MS idiopathic demyelinating disorders, specific and infectious inflammatory diseases or non-inflammatory demyelinating diseases. Clinicians should be aware of various clinical and MRI "red flags" that may point to the other diagnosis and demand further diagnostic evaluation. It is generally accepted that atypical clinical symptoms or atypical neuroimaging signs determine necessity for broad differential diagnostic work up. Of the infectious diseases that are most commonly mistaken for MS the clinician should take into account Whipple's disease, Lyme disease, Syphilis, HIV/AIDS, Brucellosis, HHV-6 infection, Hepatitis C, Mycoplasma and Creutzfeld-Jacob disease, among others. Cat scratch disease caused by Bartonella hensellae, Mediterranean spotted fever caused by Riketssia connore and Leptospirosis caused by different Leptospira serovars rarely cause focal neurological deficit and demyelinating MRI changes similar to MS. When atypical clinical and neuroimaging presentations are present, serology on rare infectious diseases that may mimic MS may be warranted. This review will focus on the infectious diseases mimicking MS with presentation of rare illustrative cases.

Abstract
Lyme disease, like syphilis, a spirochetal infection, can appear with exacerbations and remissions in different stages. The clinical picture is marked by dermatological, neurological, rheumatic and cardiological complications. PNS complications appear in the second and third stage. Tick bite meningoradiculoneuritis neuritis (Garin-Bujadoux-Bannwarth-Syndrome), characterized by painful asymmetrical sensory and motor dysfunctions and inflamed CSF, is a typical manifestation of the second stage. Mononeuritis multiplex appearing in conjunction with acrodermatitis chronica atrophicans is a typical PNS manifestation of the third stage. CNS involvement may also occur in early and late stages of Lyme-Borreliosis, presenting as myelitis or progressive encephalomyelitis. Lyme-Borreliosis is a treatable condition, which should not be missed in the differential diagnosis of PNS and CNS disorders.

Abstract
BACKGROUND:
Lyme disease (LD) is the most common tick-borne disease in the United States and in Europe. The aim of this study was to examine knowledge, perceived risk, feelings of anxiety, and behavioral responses of the general public in relation to tick bites and LD in the Netherlands.
METHODS:
From a representative Internet panel a random sample was drawn of 550 panel members aged 18 years and older (8-15 November 2010) who were invited to complete an online questionnaire.
RESULTS:
Response rate (362/550, 66%). This study demonstrates that knowledge, level of concern, and perceived efficacy are the main determinants of preventive behavior. 35% (n = 125/362) of the respondents reported a good general knowledge of LD. While 95% (n = 344/362) perceived LD as severe or very severe, the minority (n = 130/362, 36%) perceived their risk of LD to be low. Respondents were more likely to check their skin after being outdoors and remove ticks if necessary, than to wear protective clothing and/or use insect repellent skin products. The percentage of respondents taking preventive measures ranged from 6% for using insect repellent skin products, to 37% for wearing protective clothing. History of tick bites, higher levels of knowledge and moderate/high levels of worry were significant predictors of checking the skin. Significant predictors of wearing protective clothing were being unemployed/retired, higher knowledge levels, higher levels of worry about LD and higher levels of perceived efficacy of wearing protective clothing.
CONCLUSIONS:
Prevention programs targeting tick bites and LD should aim at influencing people's perceptions and increasing their knowledge and perceived efficacy of protective behavior. This can be done by strengthening motivators (e.g. knowledge, concern about LD, perceived efficacy of wearing protective clothing) and removing barriers (e.g. low perceived personal risk, not knowing how to recognize a tick). The challenge is to take our study findings and translate them into appropriate prevention strategies.

Abstract
Lyme borreliosis is a multisystem disorder caused by Borrelia burgdorferi (Bb). Neurological symptoms such as lymphocytic meningoradiculoneuritis (Bannwart's syndrome), cranial neuritis (II,III,IV,V,VI), encephalitis, transverse myelitis are found in about 10% of cases during the second phase of the disease. In the chronic stage, many months or years after the initial infection, other neurologic complications may occur, such as encephalomyelitis, epileptic crises, cognitive impairment, peripheral neuropathy and psychiatric disturbances such as depression, anxiety, panicc attacks, catatonia, psychosis etc. Some patient continue to experience symptoms of fatigue, insomnia or psychiatric disorder in the post borrelia syndrome. We describe here a patient with a triad of unusual symptoms in chronic LNB including tremor, seizures and psychosis. Standardized medical interview, neurologic examination, neuroimaging, serum and CSF serology as well as EEG and EMNG evaluation were performed. The patient was treated with intravenous ceftriaxone and doxycycline and responded with rapid clinical and functional improvement.Newertheless, he suffered from multiple systemic and neurologic sequelas that influenced his daily activities in post treatment period. Emphasis is placed on the atypical onset and evolution, the difficulties encountered in formulating diagnosis, early treatment and the uncertainties concerning the sequelae after treatment. In patients with non-specific long lasting symptoms in the absence of overt clinical signs suggesting CNS involvement, routine treatment with i.v. ceftriaxone is not to be encouraged.

Abstract
OBJECTIVE:
To evaluate the prevalence and role of psychiatric comorbidity and other psychological factors in patients with chronic Lyme disease (CLD).
METHODS:
We assessed 159 patients drawn from a cohort of 240 patients evaluated at an academic Lyme disease referral center. Patients were screened for common axis I psychiatric disorders (e.g., depressive and anxiety disorders); structured clinical interviews confirmed diagnoses. Axis II personality disorders, functional status, and traits like negative and positive affect and pain catastrophizing were also evaluated. A physician blind to psychiatric assessment results performed a medical evaluation. Two groups of CLD patients (those with post-Lyme disease syndrome and those with medically unexplained symptoms attributed to Lyme disease but without Borrelia burgdorferi infection) were compared with 2 groups of patients without CLD (patients recovered from Lyme disease and those with an identifiable medical condition explaining symptoms attributed to Lyme disease).
RESULTS:
After adjusting for age and sex, axis I psychiatric disorders were more common in CLD patients than in comparison patients (P = 0.02, odds ratio 2.64, 95% confidence interval 1.30-5.35), but personality disorders were not. Patients with CLD had higher negative affect, lower positive affect, and a greater tendency to catastrophize pain (P < 0.001) than comparison patients. All psychological factors except personality disorders were related to level of functioning. A predictive model based on these psychological variables was confirmed. Fibromyalgia was diagnosed in 46.8% of CLD patients.
CONCLUSION:
Psychiatric comorbidity and other psychological factors distinguished CLD patients from other patients commonly seen in Lyme disease referral centers, and were related to poor functional outcomes.

Abstract
From the early 90-ties there is a growing number of patients suffering from Lyme Disease all over the world, including Poland. Lyme Disease is the disorder connecting physicians of various specialties. The authors reviewed literature on mental disorders in Lyme Disease during different stages and in different types of illness. Mental disorders are part of clinical picture of the acute stage of Lyme Disease, and could also be its sequel. The most commonly found mental disorders are: encephalopathy, other cognitive disorders, mood disorders (depression), anxiety disorders and less often: psychotic disorders and eating disorders (anorexia nervosa).

Abstract
Lyme disease, which is caused by Borrelia burgdorferi and transmitted in the United States primarily by Ixodes scapularis (the deer tick), is the most common vector borne disease in the United States. Its most frequent manifestation, a characteristic, expanding annular rash (erythema migrans), sometimes accompanied by myalgia, arthralgia, and malaise, occurs in nearly 90% of persons with symptomatic infection. Other manifestations of Lyme disease include seventh cranial nerve palsy, aseptic meningitis, and arthritis. Extensive coverage in the press about the serious effects of Lyme disease has led to widespread anxiety about this illness that is far out of proportion to the actual morbidity that it causes. This problem is exacerbated by the frequent use of serological tests to eliminate the possible diagnosis of Lyme disease in persons with only nonspecific symptoms (such as arthralgia or fatigue) who have a very low probability that Lyme disease is the cause of their symptoms. Consequently, misdiagnosis is frequent and is the most common cause of failure of treatment. The prognosis for most persons with Lyme disease is excellent.
