Abstract: Modafinil is shown to be effective in improving or restoring cognitive function in the humans or other mammals when administered at doses that are substantially lower than optimal wakefulness-promoting doses. Daily dosages of less than 100 mg/day and more particularly from about 1 to about 75 mg/day are shown to be effective.

Abstract: Certain nitrogen-containing cyclohetero cycloalkylaminoaryl compounds are described for treatment of CNS disorders such as cerebral ischemia, psychotic disorders, convulsions and parkinsonism. Compounds of particular interest are of the formula ##STR1## wherein R.sup.1 is selected from hydrido, loweralkyl, cycloalkylalkyl of four to six carbon atoms and loweralkenylloweralkyl; wherein each of R.sup.2 and R.sup.3 is independently selected from hydrido and loweralkyl; wherein each of R.sup.4 through R.sup.7, R.sup.10 and R.sup.

Abstract: The invention features a method of treating a pathological condition of the prostate gland, e.g., benign prostatic hypertrophy or prostate cancer, in a mammal, said method comprising administering to said mammal a therapeutic amount of the indolocarbazole compound K-252a or a preferred derivative thereof. The invention also includes novel derivatives of K-252a.

Abstract: Compounds, compositions and methods of treatment are described to control brain damage associated with anoxia or ischemia which typically follows stroke, cardiac arrest or perinatal asphyxia. The treatment includes administration of an N-(1-thienylcycloalkyl)alkenylamine compound as an antagonist to inhibit excitotoxic actions at major neuronal excitatory amino acid receptor sites. Compounds of most interest are those of the formula ##STR1## wherein R.sup.1 is one or more groups selected from hydrido, alkyl of one to about five carbon atoms, cycloalkyl of three to about five carbon atoms, alkenyl of two to about five carbon atoms, hydroxyl and alkoxy; wherein each of R.sup.2 is one or more groups selected from hydrido, alkyl of one to about five carbon atoms, cycloalkyl of three to about five carbon atoms, alkenyl of two to about five carbon atoms, hydroxyl, oxo and alkoxy; wherein R.sup.

Abstract: Certain bridged tricyclic amine compounds are described as being therapeutically effective in treatment of CNS disorders resulting from neurotoxic damage or neurodegenerative diseases, particularly those CNS disorders resulting from ischemic events. Compounds of particular interest for use as neuroprotective agents are those of the formula ##STR1## wherein each of R.sup.1 and R.sup.2 is independently selected from hydrido, loweralkyl, benzyl and phenyl; wherein each of R.sup.1 through R.sup.7 is independently selected from hydrido, loweralkyl, hydroxy, benzyl, phenyl, loweralkoxy, phenoxy, benzyloxy, halo and haloloweralkyl; wherein R.sup.

Abstract: A method for determining a concentration of IGF-I that defines a therapeutically effective dose of IGF-I, i.e., a dose that will provide a therapeutic response in the treatment of neurological disorders for which IGF-I is utilized (including peripheral neuropathy, diabetic neuropathy, post-polio syndrome, small fiber neuropathy, ALS, and MS) is described. The method comprises determining whether a particular dose of IGF-I causes a 1.5 fold or greater increase in the homeostatic concentration of plasma IGFBP-2 in a mammal that has previously received a defined dose of IGF-I. The method of the invention can also be used to determine whether or not biological tolerance has developed to a particular dose of IGF-I.
